Question

The area of rectangle 16m by 9m. Find a square whose area is equal to rectangle by how much does the perimeter of rectangle exceed the perimeter of square

Answer 1

area of rectangle=l×b=16×9=144m^2
now according to question
area of rectangle =area of square
144=side ×side
side=√144
side=12m
perimeter of rectangle=2(l+b)
=2(16+9)
=2(25)
=50m
perimeter of square=4×side=4×12=48m


required answer=perimeter of rectangle-perimeter of square=50-48=2m
