Question

Длина прямоугольника равна 82 см ,а ширина составляет 65 процентов от его длины .ВЫЧИСЛИТЕ ПЛОЩАДЬ И ПЕРИМЕТР ПРЯМОУГОЛЬНИКА

Answer 1

1) 82 см - 100%
    х см - 65%.
Делаем пропорцию.
х= 82*65/100 =53,3 см - ширина
2) S= 82*53,3 =4370,6 см^2
3) P= (82+53.3)*2 = 270.6 cм

Answer 2

Calculation of the Area and Perimeter of a Rectangle

To calculate the area and perimeter of a rectangle, we need to know the length and width of the rectangle. In this case, the length of the rectangle is given as 82 cm, and the width is 65% of the length.

Let's calculate the width of the rectangle first:

Width = 65% of Length

To find 65% of a number, we multiply the number by 0.65.

Width = 82 cm * 0.65 = 53.3 cm

Now that we have the length and width, we can calculate the area and perimeter of the rectangle.

Area of a Rectangle

The area of a rectangle is given by the formula: Area = Length * Width.

Area = 82 cm * 53.3 cm = 4370.6 cm²

Perimeter of a Rectangle

The perimeter of a rectangle is given by the formula: Perimeter = 2 * (Length + Width).

Perimeter = 2 * (82 cm + 53.3 cm) = 2 * 135.3 cm = 270.6 cm

Therefore, the area of the rectangle is 4370.6 cm² and the perimeter is 270.6 cm.
