Question

The length of the parallel sides of a trapezium are in the ratio 3:2 and the distance between them is 10cm .If the area of trapezium is 325cm2, find the length of the parallel sides.

Answer 1

here is the answer.. ......

Answer 2

ratio between parallel side =3:2
let the common ratio be x
so parallel side are 3x and 2x
area =325cm²
$area = \frac{1}{2} (3x + 2x)10 \\ = 325 = 5(5x) \\ = 325 = 25x \\ = 13 = x$
one parallel side =3x=3×13=39cm
other =2x=2×13=26cm
