Question

The length of the parallel sides are in the ratio 7:9. It's area is 960 cm² and the distance between the parallel sides is 15 cm. Find the length of each of the parallel sides​

Answer 1

Answer:

The length of the parallel side​ are "56 cm and 72 cm".

Step by step explanation:

Given,

Area of trapezium = 960  and distance between the parallel sides = 15 cm

Let length of the parallel sides = 7x and 9x

⇒960 = 1/2 *(7x +9x) * 15

⇒(960 *2)/15 = 16 x

⇒1920/15 = 16 x

⇒128 = 16 x

⇒128/16 = x

⇒8  = x

⇒ x = 8

∴ 7x = 7*8 = 56 cm

∴ 9x = 9*8 = 72 cm

Hence,  the length of the parallel side​ are "56 cm and 72 cm".
