Question

The ratio of parallel sides of a trapezium is 5 : 3 and the distance between the parallel sides is 8cm. Find the length of the parallel sides if its area is 192cm2 .

Answer 1

Answer:

30cm and 18cm.

Step-by-step explanation:

1/2 * sum of parallel sides * height

= 1/2 * (5x+3x) * 8

=1/2 * 8x * 8

=8x * 4

=32x

32x = 192cm2

x = 192/32

x=6

Now 5x = 5*6=30cm

and 3x =3*6=18cm
