Answer 3

Calculation of Square Area

To find the area of a square, we need to know the length of one side. In this case, the perimeter of the square is given as 8 cm.

The formula for the perimeter of a square is P = 4a, where P is the perimeter and a is the length of one side.

Given that the perimeter is 8 cm, we can calculate the length of one side by dividing the perimeter by 4:

a = P/4 = 8/4 = 2 cm.

Now that we know the length of one side, we can calculate the area of the square using the formula A = a^2, where A is the area and a is the length of one side.

Substituting the value of a, we get:

A = (2 cm)^2 = 4 cm^2.

Therefore, the area of the square is 4 square centimeters.
