Question is below.

160

Step-by-step explanation:

First, to find the triangles, you would do (4x5)/2, which is 10ft^2. Since there's two triangles with the same dimensions, they're both 10ft^2 (20 in total). Counting the triangles on the other sided, all four of them add up to 40ft^2. The rectangle in the middle is 10x12, which is 120ft^2. Finally, add 120 and 40 to get 160ft^2 (but don't include the unit, in your case).
