### When Key on drew a square with an area of 225 square centimeters what is the perimerter of the square how did you get your answers?

The perimetre is 60cm.
Because a perfect square has equal sides, which are in length the
square root of the area because multiplying the length of a square
by itself gives it's area. So:
sqrt(225) = 15cm
A square has 4 sides of the same length, so if 1 side is 15cm all 4
sides that form the perimetre must be 15*4=60cm.
