Question

Find the two parallel sides of a trapezium whose area is 1.6

Answer 1

Answer:

Given area of trapezium = 1.6 sq m

Altitude, h = 10 dm = 1 m

Let one of the parallel sides be x then the other side will be (x + 0.8) m

Recall that area of trapezium, A = (1/2) * h * (a + b)

=> 1.6 = (1/2) * 1 * (x + x + 0.8)

=> 1.6 * 2 = x + x + 0.8)

=> 3.2 = 2x + 0.8

=> 2x = 3.2 - 0.8 = 2.4

Therefore, x = 1.2 m

and x + 0.8 = 1.2 + 0.8 = 2 m

Step-by-step explanation:

Thus, the parallel sides are 1.2 m and 2 m
