Question

Длина прямоугольника 7 см., а ширина 5 см. Каков периметр? Какова площадь?

Answer 1

7*5=35 площадь (7+5)*2= 24 периметр

Answer 2

Perimeter of a Rectangle

To find the perimeter of a rectangle, we can use the formula P = 2 * (length + width)

Given that the length of the rectangle is 7 cm and the width is 5 cm, we can substitute these values into the formula:

P = 2 * (7 + 5) = 2 * 12 = 24 cm.

Therefore, the perimeter of the rectangle is 24 cm.

Area of a Rectangle

The formula to calculate the area of a rectangle is A = length * width.

Using the given length of 7 cm and width of 5 cm, we can substitute these values into the formula:

A = 7 * 5 = 35 cm^2.

Hence, the area of the rectangle is 35 square centimeters.
