Question

Mohit purchase a Trapezium shaped field. It's side along the river is parallel to and twice the size along the road .If the area of the field is 10,500 m^ (2) and the perpendicular distance between two parallel sides is 100 M find the length of the side along the river.

Answer 1

area of a trapezium=(a+b/2)h

given:
a=2b
h=100m
area=10,500m^2

=>10500=(2b+b/2)100
105=3b/2
=>b=105*2/3
=35*2
=70m

=>a=70/2=35m
