A+b
A= ---------- (h)
2
So we need to plug our information in
as Depicted in the picture measurement A is first top side
And B is bottom base
so h IS the height of the figure. Its the middle line in the middle of the figure.
10+15
A= ________(7)
2
10+15=25
25*7=175
175/2=87.5
So your answer is
Area of ABCD is 87.5
