Question

8. 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 mº and the perpendicular distance between the two parallel sides is 100 m, find the length of the side along the river.​

Answer 1

Area = 1/2*height*(sum of parallel sides)

10500=1/2*100*(x+2x)

10500*2/100=3x

210=3x

x=70

2x=140
