Question

The parallel sides of a Trapezium are in the ratio 2:5 and the distance between the parallel sides is 10 cm if the area of the trapezium is 350 CM square find the length of its parallel sides

Answer 1

Let one side be(a)=2x

another side be(b)= 5x and height (h)=10cm.

Area of trapezium =350cm^2 .

i e.h/2(a+b)=350

10/2(2x+5x)=350

5(7x)=350

there fore x=10

One side (2x)=2*10=20

another side (5x)=5*10=50.

Answer 2

2x and 5x are the parallel sides.

(1/2)(7x)(10)=350

x=10.

Therefore, parallel sides, 2x=20

5x=50
