Question

Mohan wants to buy a trapezium shaped field. Its side along the river is parallel to and twice the side along the road. If the area of this field is 10500 m² and the perpendicular distance between the two parallel sides is 100 m, find the length of the side along the river.

Answer 1

Given: Perpendicular distance h = 100 m 

Area of the trapezium shaped field = 10500 m² 

Let side along the road be x m and side along the river = 2x m

Hence, the side along the river = 2x = 2 x 70 = 140 m.
