Question

Find the length of the base of a parallelogram if the area of the parallelogram is 72cm$^{2}$and its altitude is twice the corresponding base.

Answer 1

Area of the parallelogram =72cm²

Height =2b

Base=?

Area of parallelogram =b*h

72=b*2b

72=2b²

b²=72/2

b²=36

b=√36

b=6

.

. . h=2b

=2*6

h =12

The length of the base =6 cm
