The perimeter of the square is 20 cm. A rectangle was made from two such squares.

The perimeter of the square is 20 cm. A rectangle was made from two such squares. Find the perimeter and area of this rectangle.

The size of the perimeter of a square is the size of its side multiplied by 4. Find the length of the side:

a = P / 4 = 20/4 = 5 cm.

After two such squares were folded, we got a rectangle whose length is 2 times the side of the square, and the width is equal to the length of the side of the square.

b = 10 cm.

c = 5 cm.

Find the perimeter and area of the rectangle:

PP = 2 * (b + c) = 2 * 15 = 30 cm.

S = b * c = 50 cm².
