Answer: 44 m

Step-by-step explanation:

Given

The area of the trapezium is A=480\ m^2

Distance between parallel sides h=15\ m

One of the parallel sides is 20\ m

Suppose the other parallel side is x

The area of the trapezium is

A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h

Put values

\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m
