Mohan wants to buy a trapezium shaped field. Its side along the river isparallel to and twice the side along the road. If the area of this field is 10,500 m² and theperpendicular distance between the two parallel sides is 100 m, find the length of theside along the river.​

Answer»

Answer:

Heya Here's your answer mate

Let the parallel sides of the trapezium-shaped field be ′x ′ m and ′2x ′ m.

Let a=x and b=2x and h=100m

Then, its AREA.

= 1 /2(a + b) x hm²

= 1 /2 (x + 2x) x 100 m²

=50 x 3X m² = 150X m²

But it is given that the area of the field is 10500 m²

Therefore, 150x = 10500

X = 10500 / 150 = 70 m

Thus The length of the side along the river is 2 x 70, i.e., 140 m.

Thanks

have a great day ahead
