A square patio has an area of 225 square feet. Write the area as a power. Then find the side lengths of the patio.

Write the area as a power: 15^2
Then find the sidelength of the patio: Each side is equal to 15

Reasoning:

A square has four equal sides and to work out area the formula is length x witdth, hence the length and width values are equal. This could also be written as length^2.

Since the area of the patio is 225, the square root of this would give each side length. Henceforth the square root of 225 is equal to 15. A square has four equal sides and to work out area the formula is length x witdth, hence the length and width values are equal. This could also be written as length^2.
