Question

A square carrom board has a perimeter of 320 cm. How much is its area?

Answer 1

perimeter of a carrom board= 320
                                4s= 320cm
                                 s=320/4
                                  s= 80cm
area of sq. carrom board = s x s
                                         =80 x 80 sq.cm
                                         =6400 sq.cm

Answer 2

sum of sides of square = 320
one side= 320÷4=80
area=side×side
=80×80
=6400cm2
