The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel side is 20m. Find the other parallel side
Answers: 3
![A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h](/tpl/images/1256/4191/8f3d0.png)
![\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m](/tpl/images/1256/4191/4d14f.png)
