The area of the square is 25 cm2. What are the sides of the square. Find the perimeter of the given square.

In order to find the side of a square, and then its perimeter, we will remember the formula for finding the area of a square and express the side from it.

Let’s see what we know from the condition. It says that the area of a square is 25 cm2.

The area of a square is equal to the square of its side.

S = a ^ 2;

Let us express the side from the formula and calculate it:

a = √S;

a = √25 = 5 cm side of the square.

We have completed half of the task.

Now let’s remember and apply the formula for finding the perimeter:

P = 4a = 4 * 5 = 20 cm perimeter of the square.
