A square has an area of 36 ft2. What is the perimeter of the square? Show or explain your answer.

Step-by-step explanation:

We are asked to find the perimeter of a square. The perimeter is the sum of all the sides in a shape. Since a square is made of 4 equal sides, we can add the sides or just multiply a side length by 4.

However, we are given the area. We must solve for the side length. The formula for calculating the area of a square is:

We know the area of the square is 36 square feet. We can substitute this value in for a.

We are solving for the side, so we must isolate the variable s. It is being squared. The inverse of a square is the square root, so we take the square root of both sides of the equation.

Now we know the side length is 6 feet, and we can substitute this into the perimeter formula.

Multiply.

The perimeter of the square is 24 feet.
