Question

Из прямоугольника со сторонами 11 и 8 см вырезали 2 квадрата со стороной 5см каждый. найди площадь оставшейся фигуры

Answer 1

1) 11*8= 88(см2)- площадь прямоугольника 2)5*5=24(см2)- площадь одного квадрата 3)24+24=48(см2)- площадь двух квадратов 4) 88-48=40(см2) ответ:40 см2

Answer 2

Problem Analysis

We are given a rectangle with sides measuring 11 cm and 8 cm. Two squares with sides measuring 5 cm each have been cut out from the rectangle. We need to find the area of the remaining figure.

Solution

To find the area of the remaining figure, we need to subtract the sum of the areas of the two squares from the area of the original rectangle.

Let's calculate the area of the original rectangle first.

The formula to calculate the area of a rectangle is given by: Area = length * width

Given that the length of the rectangle is 11 cm and the width is 8 cm, we can calculate the area as follows: Area of the rectangle = 11 cm * 8 cm = 88 cm^2.

Now, let's calculate the area of the two squares that were cut out.

The formula to calculate the area of a square is given by: Area = side * side

Given that the side of each square is 5 cm, we can calculate the area of one square as follows: Area of one square = 5 cm * 5 cm = 25 cm^2

Since two squares were cut out, the total area of the two squares is: Total area of the two squares = 2 * 25 cm^2 = 50 cm^2

To find the area of the remaining figure, we need to subtract the total area of the two squares from the area of the original rectangle: Area of the remaining figure = Area of the rectangle - Total area of the two squares = 88 cm^2 - 50 cm^2 = 38 cm^2

Therefore, the area of the remaining figure is 38 cm^2.

Answer

The area of the remaining figure after cutting out two squares with sides measuring 5 cm each from a rectangle with sides measuring 11 cm and 8 cm is 38 cm^2.
