Answer:
Step-by-step explanation:
a and b are the parallel sides of the trapezoid.
In the graph, each unit = 2
a = 8 & b= 4
height = h = 8
![\bf \boxed{ \text{Area of trapezoid = $\dfrac{(a+b)*h}{2}$} }](https://tex.z-dn.net/?f=%5Cbf%20%5Cboxed%7B%20%5Ctext%7BArea%20of%20trapezoid%20%3D%20%24%5Cdfrac%7B%28a%2Bb%29%2Ah%7D%7B2%7D%24%7D%20%7D)
![\bf = \dfrac{(8+4)*8}{2}\\\\\\ = \dfrac{12*8}{2}\\\\\\ = 6*8\\\\ = 48 \ square \ units](https://tex.z-dn.net/?f=%5Cbf%20%3D%20%5Cdfrac%7B%288%2B4%29%2A8%7D%7B2%7D%5C%5C%5C%5C%5C%5C%20%20%20%20%20%20%3D%20%5Cdfrac%7B12%2A8%7D%7B2%7D%5C%5C%5C%5C%5C%5C%20%20%20%20%20%20%3D%206%2A8%5C%5C%5C%5C%20%20%20%20%20%20%20%3D%2048%20%5C%20square%20%5C%20units)
