Question

The area of trapezium is 360m². The ratio of the parallel sides 3:1. if the distance between the parallel sides is 30 cm find the length of the parallel sides​

Answer 1

Answer:

Given,

Area of trapezium =360m

2

Distance between two parallel lines =20m

One parallel side =25m

Let's assume the second parallel side to be x m

∴ Area =(25+x)×20

⇒360=(25+x)×20

⇒x=36−25=11m

Therefore, the second parallel side is 11m
