The diagram shows a triangle on top of a rectangle. The combined area of the triangle and rectangle is 108 ft2
podryga [215]

Answer:

6 ft

Step-by-step explanation:

A=1/2bh. To find the area of the triangle, we subtract the area of the rectangle from the total. Which would be 108 - (12x6) = 36. Now we have the area. So, 36 = 1/2bh. "b", the base is 12. So we solve for h. h = (36x2)/12 or h = 36/6, which both equal 6.
