1.	Parallel sides AD and BC.The area of a trapezium is 540 cm. If its parallel sides are in the ratio 7:5 and the distance between them is18 cm, find the lengths of the parallel sides.
Answer» ANSWER: AR. of trapezium = 1/2 × H ×(a+b) 1/2 × 18 (7a+5a) = 540 cm × cm 12a = 540 ×18/2 a = 60/12 a = 5 7a = 35 cm 5a = 25 cm

Parallel sides AD and BC.The area of a trapezium is 540 cm. If its parallel sides are in the ratio 7:5 and the distance between them is18 cm, find the lengths of the parallel sides.

Answer»

ANSWER:

AR. of trapezium = 1/2 × H ×(a+b)

1/2 × 18 (7a+5a) = 540 cm × cm

12a = 540 ×18/2

a = 60/12

a = 5

7a = 35 cm

5a = 25 cm
