Mohan wants to buy a trapezium shaped field. Its side along the river is parallel 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.
Let the length of side of trapezium shaped field along road =
Length of other side of trapezium shaped field along road =
Area of trapezium = 10500 cm2
Distance between parallel sides = 100 m
Area of trapezium =
Therefore length of side along road = 70 m
Length of side along river = 70× 2 = 140 m
