What is the area of a square if its side is one-fifth of a meter?

First, we can calculate the length of the side of the square, if it is known that it is a fifth of a meter:

100 * 1/5 = 20 cm.

The area of a square is calculated by squaring the length of its side. Thus, we can calculate the area of a square if we know the length of its side:

S = 202 = 400 cm2.

Answer: the area of the square is 400 cm2.
