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
=12× Sum of the length of the two parallel sides × Distance between the two parallel sides.
Hence,
600 = 12 (a + 20) × 15
a + 20 = 80
a = 80 – 20 = 60
Hence, the length of the other parallel side = 60 m
