Solution

The correct option is C
60m

Let the length of the other parallel side be a.
Given, one of the sides is 20 m and the distance between two parallel sides is 15 m.

The area of trapezium is given by
$= \frac{1}{2} \times$ Sum of the length of the two parallel sides $\times$ Distance between the two parallel sides.

Hence,

600 = $\frac{1}{2}$ (a + 20) × 15

a + 20 = 80

a = 80 – 20 = 60

Hence, the length of the other parallel side = 60 m
