Question

Длинна прямоугольника 9 см, ширина составляет 1/3 от длины.Найти периметр прямоугольника?

Answer 1

1) 9*1/3 = 3 см ширина

2) (9+3) * 2 = 12*2 = 24 см - периметр

Answer 2

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle when the length is 9 cm and the width is 1/3 of the length, we can use the formula:

Perimeter (P) = 2 * (length + width)

Given that the length is 9 cm and the width is 1/3 of the length, we can calculate the width as follows:

Width = 1/3 * Length Width = 1/3 * 9 Width = 3 cm

Now, we can calculate the perimeter using the formula:

P = 2 * (9 + 3) P = 2 * 12 P = 24

Therefore, the perimeter of the rectangle is 24 cm.

This calculation is based on the formula for the perimeter of a rectangle and the given dimensions of the rectangle
