Question

Suppose a squad patio has an area of 441 square feet. Use the formula for the area of a square to find the length of each side of the patio.

Answer 1

For a square:
`A=s^(2)`

Solve for the length of a side by taking the square root of both sides:

`√(A)=\sqrt{s^(2)}`

`√(A)=s`

Now we can substitute known values:

`s=√(A)`

`s=\sqrt{441ft^(2)}`

`s=21ft`
