Question

A rectangle has dimensions 12cm*6cm.if you draw a square of the same parameter.what will its area be?

Answer 1

Perimeter of rectangle =2(l+b)

                                     =2(12+6)

                                     =2*18

                                      =36cm-------answer

So perimeter of squre=36cm

Side of a sqare is  = perimeter/4

                              =36/4

                              =9cm

Area of square = side*side

                        =9*9

                        =81cm^2
