Question

length of the parallel sides are in the ratio 7 : 9 its area is 960 CM square and its distance between the parallel sides is 15 cm find the length of each of the parallel side​

Answer 1

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

Step-by-step explanation:

Given,

Area of trapezium = 960 $cm^{2}$ and distance between the parallel sides = 15 cm

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

$Area of trapezium =\frac{1}{2} \times (Sum of parallel sides)\times Distance between them$

⇒$960 =\frac{1}{2} \times (7x + 9x)\times 15$

⇒$8x = \frac{960}{15} =64$

⇒ x = 8

∴ $7x = 7\times 8 =56 and 9x = 9\times 8 =72$

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