Question

The area of trapezium is 180cm^2 and distance between two parallel sidesd is 12 cm. If one of the parallel sides is double the other . Find the measure of parallel sides.

Answer 1

Answer:

Step-by-step explanation: Let one of the parallel side be x; then the other side will be 2x

Area of a trapezium =1/2 ( sum of parallel sides) x height

180 = 1/2 (X +2x) x 12

180 = 6(3x)

30= 3x

x = 10.

Hence one of the parallel lines is 10 and the other side is 20
