Question

A rectangle and parallelogram are drawn between the same parallel lines on a common​ base 10cm. If the perimeter of the rectangle is 36cm. Find the area of the parallelogram

Answer 1

base=10cm
take base as l
Perimeter=2(l+b)
36=2(10+b)
2b=16
b=8
area of rectangle =l×b
=10×8=80
area of rectangle and parallelogram will be same so area of parallelogram will be 80
