Question

в мастерской сделали квадратную и прямоугольную рамку длина прямоугольной рамки 10см.ширина 8см .на квадратную рамку материала пошло столькоже .сколько и на  прямоугольную. какая длина стороны квадратной рамки

Answer 1

1) (10+8)*2 = 36(см) периметр
2) 36 : 4 = 9(см) сторона квадратной рамки

Answer 2

Calculation of Material for Square and Rectangular Frames

To calculate the amount of material required for both the square and rectangular frames, we need to consider the dimensions of the rectangular frame and the fact that the same amount of material was used for the square frame.

Given: - Length of the rectangular frame = 10 cm - Width of the rectangular frame = 8 cm

We can assume that the material used for the square frame is the same as that used for the rectangular frame. Therefore, the amount of material used for both frames is equal.

To find the length of the side of the square frame, we can use the formula for the area of a rectangle:

Area of a rectangle = length × width

Since the area of the rectangular frame is equal to the area of the square frame, we can set up the following equation:

10 cm × 8 cm = x cm × x cm

Simplifying the equation:

80 cm² = x² cm²

Taking the square root of both sides to solve for x:

x = √80 cm ≈ 8.94 cm

Therefore, the length of each side of the square frame is approximately 8.94 cm.

Please note that the above calculation assumes that the frames are two-dimensional and have negligible thickness. If the frames have a significant thickness, the calculation may need to be adjusted accordingly.
