Question

the lengths of two parellel edges of a railway platform are 100m and 132m. each of the remaining two non parellel but equal sides are 20m long, then find the area of platform.

Answer 1

Here two tracks are parallel to each other and other two are equal so fig act as a trapezium
so, area of trapezium = 1/2×(sum of parallel sides)×non parallel sides
=1/2×(100+132)×20
=1/2×232×20
=2320
