Example. The area of a square with a side of 5 cm is 25 cm². How many square decimeters is that?

Note, that there are 100 square decimeters (dm²) in 1 square meter (m²). Solution. 1 dm² = 10 cm * 10 cm = 100 cm².

25 cm² = 25 / 100 dm² = 0.25 dm²

Let's consider an example. The area of the given rectangle is three square centimeters. This means that the rectangle can contain three squares, each with a side length of one centimeter. If we examine how many times a square with a side length of one centimeter fits into the rectangle, we find that it fits three times.

Now, suppose we have another rectangle with an area of six square centimeters. This means it can contain six squares, each with a side length of one centimeter. Let’s say we need to measure the area of a certain room.

To measure this area accurately, it is convenient to use square decimeters. Our task is to determine how many squares with a side of one decimeter (1 dm²) can fit into the room. After filling the entire room with these squares, we find that a square decimeter fits into the room 1200 times. This means that the area of the room is 1200 square decimeters.

In the previous example, we calculated the room's area by systematically checking how many times it contained a square with a side of one decimeter. The result was 1200 square decimeters. Since the room is a rectangle, we can calculate the area by multiplying its length and width.

Now return to the upper example. Suppose we measured the room's length using a tape, and the length turned out to be 40 decimeters. Now, we measure the width, which is 30 decimeters. By multiplying the length (40 dm) by the width (30 dm), we get: 40 × 30 = 1200 square decimeters. This calculation shows how many square decimeters fit within the room, confirming our previous result.

To further explain, by measuring the length, we can determine how many squares with a side of one decimeter can fit into that length. If we visualize laying out four squares along this length, we then measure the width of the rectangle to see how many times this length can be repeated.

Let's analyzethe area of a square. A square is a some type of rectangle where all sides are equal. For example, consider a square with a side length of 3 cm. The phrase "square with a side of 3 cm" indicates that all sides measure 3 cm. The area of a square can be calculated in the same manner as that of a rectangle, by multiplying its side lengths.

To calculate the area of a square with a side length of 3 cm, we multiply the length of 3 cm by itself:
3 × 3 = 9. Thus, a square with a side length of 3 cm contains nine smaller squares, each with a side of 1 cm. Indeed, this is accurate. By multiplying the length by itself, we create the expression 3 × 3, which describes the area of the square as 3 squared, or 3^2. This notation indicates the second power of the number 3. Therefore, the term "squaring a number" refers to calculating the area of a square with that number as its side length.

In mathematical terms, the area is denoted by the capital letter S. Consequently, for a square with a side length of a centimeters, the area can be foind out using the formula S = a^2, where a represents the length of the side of the square. The square, in this case, has equal lengths and widths, both represented by a. If we need to determine how many squares with a side length of 1 cm fit into the larger square, we should use cm² as the unit of area measurement.

The area of a figure is a positive value defined for each figure such that:

Equal figures have equal areas.
If a figure is composed of a finite number of figures, its area equals the sum of their areas.

Let us agree to denote the area of a figure as S. To measure the area of a figure, you need to have a unit of area. As a rule, the unit of area is the area of a square with a side equal to a unit segment, i.e., a segment chosen as a unit of length.

Measuring the area consists of comparing the area of a given figure with the area of a unit square e2. The result of this comparison is a number x such that S(F) = xe². x is the numerical value of the area for the chosen unit of area.

One method based directly on the definition of area is measuring it using a palette—a grid of squares applied to a transparent material.

Let us assume that a grid of squares with a side of e is imposed on a figure F, the area of which needs to be measured. Then, about this figure, we can distinguish two types of squares:

squares that lie entirely inside the figure F;
squares through which the outline of the figure passes and which lie partly outside and partly inside the figure F.

Let m be squares of the first type, and n be squares of the second type. Then, the area of the figure F will satisfy the condition m2 <S(F)<(m+n)e2. The numbers m and m+n will be approximate numerical values of the measured area: the first number with a deficiency, the second with an excess.

To obtain a more accurate result, we can compact the original grid of squares by dividing each into smaller squares. For example, we can construct a grid of squares with a side of e1 = 1/10 ∙ e. As a result, we will obtain other approximate values of the area of Figure F with greater accuracy. The described process can be continued.

The technique of measuring the area of figures using a palette has limited application; it can be used only for small areas. Therefore, in mathematics, since its inception, there has been a search for indirect ways to measure area by measuring the lengths of the sides, heights, and other segments belonging to a figure. For example, the numerical value of the area of a rectangle is found by multiplying the numerical values of the lengths of its sides.

Some properties of areas:

1. If figures are equal, then the numerical values of their areas are equal (with the same unit of area).

Figures with equal areas are called equal.

2. The numerical value of the area of a figure is equal to the sum of the numerical values of the regions of its constituent parts (with the same unit of area).

3. When replacing a unit of area, the numerical value of the area increases (decreases) as many times as the new unit is smaller (larger) than the old one.
