91 yd^2
Break it up into separate shapes that you know how to take the area of.
For the top, you could draw a line to esperare a triangle shape from a red tangle shape
The triangle is 6 yd tall and 13 yd long.
A= 1/2bh which in this case is 6(1/2)(13)=39
Then do your rectangle A= bh, in this case (13)(4)= 52
Add them to get your answer: 52+39=91 :)
