Question

В мастерской сделали квадратную и прямоугольную рамки для портретов. Длина прямоугольной рамки 10 см, а ширина 8 см. На квадратную рамку материала пошло столько же, сколько и на прямоугольную. Вычисли длину стороны квадратной рамки.

Answer 1

(10+8)*2=36
36/4=9
9см сторона квадратной рамки

Answer 2

10×2+8×2=36
36/4=9
Ответ 9

Answer 3

Calculation of the Side Length of the Square Frame

To calculate the side length of the square frame, we need to determine the amount of material used for both the square and rectangular frames.

Given that the rectangular frame has a length of 10 cm and a width of 8 cm, and the same amount of material is used for the square frame, we can calculate the total amount of material used.

According to the search result snippet from the total amount of material used for both frames is 36 cm.

To find the side length of the square frame, we can divide the total amount of material used by 4, since a square has four equal sides.

Using the calculation from the same search result snippet, 36 cm divided by 4 equals 9 cm.

Therefore, the side length of the square frame is 9 cm.
