Question

The area of the trapezium is 480m2 the distance between two parallel sides is 15m.The longer parallel side is longer than the other by 44m,find the length of the parallel side

Answer 1

the length of the parallel side is 20 m.

soln:

let, the parallel side be a.

1\2(a+44)15=480

or,(a+44)15=(480)(2)

or,(a+44)=960\15

or,a=64-44

or,a=20

therefore, the length of the parallel side is 20m.
