Question

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

Answer 1

base is 10 cm
rectangles base will also be 10 cm(because same base)
so
perimeter=36 cm
2(l+b)=36
2(10+b)=36
10+b=36/2
b=18-10
b=8
So area of rectangle=8 x 10=80cm^2
area of paralellogram=area of rectangle (because they are on same base and between same parallel)
area of paralellogram=80cm^2

Answer 2

Step-by-step explanation:

area of parallelogram=80cm^2
