A square patio has a area of 215 square feet. how long is each side of the patio to the nearest 0.05

Vanyuwa [196]

A square has all 4 sides the same.

When given the area of a square , you can find the length of the side by finding the square root of the area:

Side length = √215

Side Length = 14.6628

Rounding to the nearest 0.05 would = 14.65 feet.
