Question

Из прямоугольника со сторонами 12 см и 13 см вырезали квадрат со стороной 11 см. Найти площадь оставшейся фигуры.

Answer 1

1) S всего прямоугольника= 12х13=156
2)S квадрата= 11х11=121
3) S = 156-121= 35

Answer 2

Calculation of the Remaining Figure's Area

To find the area of the remaining figure after a square with a side length of 11 cm is cut out from a rectangle with sides measuring 12 cm and 13 cm, we can subtract the area of the square from the area of the rectangle.

The area of a rectangle is given by the formula: Area = length × width.

Given that the rectangle has sides measuring 12 cm and 13 cm, the area of the rectangle is:

Area of Rectangle = 12 cm × 13 cm.

Now, let's calculate the area of the square that was cut out. The area of a square is given by the formula: Area = side × side.

Given that the square has a side length of 11 cm, the area of the square is:

Area of Square = 11 cm × 11 cm.

To find the area of the remaining figure, we subtract the area of the square from the area of the rectangle:

Area of Remaining Figure = Area of Rectangle - Area of Square.

Let's calculate the area of the remaining figure:

Area of Remaining Figure = (12 cm × 13 cm) - (11 cm × 11 cm).

Calculating the values:

Area of Remaining Figure = 156 cm² - 121 cm².

Area of Remaining Figure = 35 cm².

Therefore, the area of the remaining figure is 35 cm².
