Area of a square 64. Find the area of a rectangle whose perimeter is equal to the perimeter

Area of a square 64. Find the area of a rectangle whose perimeter is equal to the perimeter of this square, and the sides are 2: 6.

1) Find out the length of the side of the square.

√64 = 8 cm.

2) Find out the perimeter of the square.

8 * 4 = 32 cm.

3) Let us denote the relations of the perimeter as x.

2x: 6x

4) Let’s compose and solve the equation:

2 * (2x + 6x) = 32;

16x = 32;

x = 32: 16

x = 2

5) Find out the width of the rectangle.

2 * 2 = 4 cm.

6) Find out the length of the rectangle.

2 * 6 = 12 cm.

Answer: width 4 cm, length 12 cm.
