Question

The area of a trapuezimu is 150cm^2. if one of the parallel sides is 28cm and the distance between the parallel sides is 5cm, so find the length of the other parallel side .​

Answer 1

$\bold{Answer:-}$

Given:

Area of the trapezium = 105cm^2

One of its parallel sides = 28cm

Distance between the parallel sides = 5cm

Length of other parallel side =?

Let the length of other parallel side be 'x'.

We know that,

Area of a trapezium = 

1/2 *(sum of parallel sides)*height

According to question,

105cm^2 = 1/2*(28 + x)*5

105 * 2 / 5 = 28 + x

21 * 2 = 28 + x

42 - 28 = x

x = 14cm..
