Question

if the area of a square field is 225m.sq .then it's perimeter is ​

Answer 1

area of square = (side)²

here area is 225

225 = (side)²

side = 15

now, perimeter of a square is 4*side

perimeter of the square = 4*15

= 60m.sq

Answer 2

Area of square = s^2 = 225

s = root 225 = 15m

Perimeter of square = 4s = 4 x 15 = 60m.
