The perimeter of the square is 8 m from two such squares made a rectangle, find the area of the rectangle.

First, find the side of the square.

We know that its perimeter is 8 m, it is calculated by the formula:

P = 4a. Therefore, the unknown in this case is the quotient of the product and the first factor:

a = P: 4 = 8: 4 = 2 m.

A rectangle was made up of two such figures, which means its width = 2 m, and length = 2 + 2 = 4 m.

Since the opposite sides are equal, the area corresponds to the formula:

S = a * b = 2 * 4 = 8 m².
