The area of a trapezium is 360 m², the distance between two parallel sides is 20 m and one of the parallel side is 25 m. Find the other parallel side.

$\huge \mathbb \green{Required \: Answer}$⤵️

Let the other parallel side be x.

Formula to find area of trapezium:-

$\huge \pink{Area = \frac{a + b}{2} \times h}$

Given,

Area=360m^2

Parallel sides=25m,x

Height=20m

Putting the values in formula:-

$\red{{360} = \frac{25 + x}{2} \times 20}$

$\pink{ \frac{360}{20} = \frac{25 + x}{2} }$

$\pink{18 \times 2 = 25 + x} \\ \pink{36 = 25 + x} \\ \pink{x = 36 - 25} \\ \\ \huge \mathbb\red{x = 11}$

Another Parallel side = 11m
