Question

Одна клетка тетради представляет собой квадрат со стороной 5 мм. вычисли его площадь в квадратных миллиметрах. чему равна площадь фигуры, состоящей из двух таких квадратов, трёх квадратов, четырех квадратов

Answer 1

S=a*b
5*5=25 мм квадратных
25*2=50 мм квадратных
25*3=75 мм квадратных
25*4=100 мм квадратных

Answer 2

5мм*5мм= 25 кв.мм
5мм*10мм= 50 кв.мм
5мм*15мм=75 кв.мм
10мм*10мм= 100 кв.мм

Answer 3

Calculation of the Area of a Single Cell

To calculate the area of a single cell in a notebook, we need to determine the area of a square with a side length of 5 mm. The formula for calculating the area of a square is:

Area = side length * side length

Substituting the side length of 5 mm into the formula, we get:

Area = 5 mm * 5 mm

To calculate the area in square millimeters, we need to convert the units. Since 1 mm is equal to 1/1000 of a meter, we can convert the area to square millimeters by multiplying by the conversion factor:

Area = (5 mm * 5 mm) * (1 mm/1 mm^2)

Simplifying the equation, we get:

Area = 25 mm^2

Therefore, the area of a single cell in the notebook is 25 square millimeters.

Calculation of the Area of Figures Consisting of Multiple Cells

To calculate the area of a figure consisting of multiple cells, we need to know the number of cells in the figure. Let's consider the figures consisting of two, three, and four cells.

1. Figure consisting of two cells: - To calculate the area of this figure, we need to add the areas of the two individual cells. - Since each cell has an area of 25 square millimeters, the total area of the figure consisting of two cells is 50 square millimeters.

2. Figure consisting of three cells: - To calculate the area of this figure, we need to add the areas of the three individual cells. - Since each cell has an area of 25 square millimeters, the total area of the figure consisting of three cells is 75 square millimeters.

3. Figure consisting of four cells: - To calculate the area of this figure, we need to add the areas of the four individual cells. - Since each cell has an area of 25 square millimeters, the total area of the figure consisting of four cells is 100 square millimeters.

Therefore, the areas of the figures consisting of two, three, and four cells are 50 square millimeters, 75 square millimeters, and 100 square millimeters, respectively.
