Question

В мастерской зделали квадратную и прямоугольную рамкидля портретов длина 10 см а ширина 8 см на квадратную рамку матерьяла пошло сколко же и на прямоугольник вычесли длину стороны квадратной рамки

Answer 1

Pпр=2(a+b)
P=2(10+8)=36см
Pкв=4a
Pкв=Pпр=36см
а=Ркв:4
а=36:4=9(см)
Ответ:длина стороны квадратной рамки равна 9 см.

Answer 2

2*(10+8)=2*18=36 см периметр прямоугольной рамки
36:4=9 см длина стороны квадратной рамки

Answer 3

Calculation of Material for Square Frame:

To calculate the amount of material required for the square frame, we need to find the perimeter of the frame. The formula for the perimeter of a square is 4 * side length.

Given that the side length of the square frame is 10 cm, we can calculate the perimeter as follows:

Perimeter of the square frame = 4 * 10 cm = 40 cm.

Therefore, 40 cm of material is required for the square frame.

Calculation of Material for Rectangular Frame:

To calculate the amount of material required for the rectangular frame, we need to find the perimeter of the frame. The formula for the perimeter of a rectangle is 2 * (length + width).

Given that the length of the rectangular frame is 10 cm and the width is 8 cm, we can calculate the perimeter as follows:

Perimeter of the rectangular frame = 2 * (10 cm + 8 cm) = 2 * 18 cm = 36 cm.

Therefore, 36 cm of material is required for the rectangular frame.

In summary, 40 cm of material is required for the square frame, while 36 cm of material is required for the rectangular frame.
