Given:
In Trapezium, one of the parallel sides is twice the other
Let one side of the parallel side be x
distance between the two parallel sides is 84 m
Area of the field =9450 m2
Since, Area of the trapezium
=12×Sum of the parallel sides×Distance between the two parallel sides
⇒12×(x+2x)×84 m=9450 m2
⇒3x×42 m=9450 m2
⇒x=9450 m23×42 m
⇒x=75 m [First side]
⇒2x=2×75 m=150 m [Second side]
