Answer:

$A_(total) = 132\ ft^2$

Explanation:

Step 1: Determine the area of the rectangle

A = l * w

$A = 9\ ft * 11\ ft$

$A = 99\ ft^2$

Step 2: Determine the area of the triangles

A = (h * b)/(2)

$A=((15\ ft - 9\ ft)*(11\ ft / 2))/(2)$

$A=(6\ ft * 5.5\ ft)/(2)$

$A = 16.5\ ft^2$

Since we found only one of the right triangles we need to multiply the area that we got by 2 to get the total triangle area.

$A = 16.5\ ft^2 * 2$

$A = 33\ ft^2$

Step 3: Determine the total area

$A_(total) = 99\ ft^2 + 33\ ft^2$

$A_(total) = 132\ ft^2$

Answer:
$A_(total) = 132\ ft^2$
