Answer: 44 m
Step-by-step explanation:
Given
The area of the trapezium is 
Distance between parallel sides 
One of the parallel sides is 
Suppose the other parallel side is 
The area of the trapezium is
![A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20%5B%5Ctext%7BSum%20of%20parallel%20sides%7D%5D%5Ctimes%20h)
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](https://tex.z-dn.net/?f=%5CRightarrow%20480%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20%5B20%2Bx%5D%5Ctimes%2015%5C%5C%5C%5C%5CRightarrow%20480%5Ctimes%202%3D300%2B15x%5C%5C%5CRightarrow%20960-300%3D15x%5C%5C%5CRightarrow%20x%3D44%5C%20m)
