Question

The area of trapeziun 540cm .if the ratio of parallel sides is 7 :5 and the distance between them is 18 cm .Find the area of the trapezium

Answer 1

We know that , Area if trapezium = 1/2 * sum of parallel sides * height

Let the parallel sides be 7x and 5x

540 = 1/2 * (7x + 5x) * 18
540/18 = 1/2 * 12x
30*2 = 12x
60= 12x
X= 5

Therefore,
7x = 35 cm
and 5x = 25cm
