Question

Perimeter of a square whose area is 225cm

Answer 1

Step-by-step explanation:

area = 225cm²

a² = (15)²

a = 15 cm

perimeter of this square = 4*a

= 4*15 = 60cm

Answer 2

Let the side of square be x,

Area of square=Side×Side

225= x×x

225=x^2

√225=x

x=15

therefore side is 15cm

Perimeter of square=4×side

=4×15

=60cm
