Question

The area of a trapezium is 180 cm and its height is 12 cm. If one of the parallel sides
is double the other side, find the two parallel sides.
find the altitude of a trapeziumth​

Answer 1

Answer:

the sides are 10cm and 20cm

Step-by-step explanation:

let ABCD be the trapezium ...AB and CD be the parallel sides=x and AL be the height

Acc. to Q AB is double  CD

let AB = x then CD = 2x

Ar. of trapezium = 180 = 1/2(AB+CD)*AL

1/2(x+2x)*12=180

3x*6=180

18x=180

x=10

AB=10cm

CD=20cm
