To find the length of each side of a square when you know the area, you can use the formula for the area of a square, which is:
A = s²
where A is the area and s is the length of a side. In this case, we know that the area (A) is 144 square feet:
144 = s²
To find the length of one side (s), you need to take the square root of the area:
s = √144
Calculating this gives us:
s = 12
Thus, each side of the square is 12 feet long. This is because a square has equal sides, and since the area is a product of the side lengths, each side must be 12 feet for the area to equal 144 square feet.
