Question

the area of a Trapezium is 720 CM square if the ratio of parallel side is 9 is 28 and the distance between them is 12 CM then find the parallel side​

Answer 1

Answer:

area of trapezium= 1/2 *b (a*b)

720 = 1/2 * 12 (9x + 28x)

720 = 6 (9x+28x)

720/6 = 9x+28x

120 = 9x+28x

120 = 37x

120/37 = x
