Answer:
60
Explanation:
Ok. first you want to determine the size of each side. 5 x 9 = 45 gets you the rectangle. You already have the tricky part, which is getting the width of the triangle. Now what you do is add 2.5 + 2.5 + 5 for the length, then you can do simple math and say 2.5 + 2.5 + 5 = 10
10 x 3 = length x width = 30, but since it's a triangle divide it by 2 and you'd get 15.
Now all you do is add them together and you get 60
