Question

If perimeter of a rectangle is 36 m and its breadth is 8 m, then its area is

Answer 1

Perimeter of rectangle=2(l+b)
=2(l+8)=36
L=10m
Area=l*b
=10*8
=80m^2

Answer 2

Perimeter of rectangle = 2 (l+b)
36m=2 (l+8)
36=2l+16
2l=36-16
2l=20
l=20/2=10m
area of rectangle =l×b
area = 8×10
area = 80m^2
