The answer is a. 385 ft is the answer because 11x11 plus 11x12/2 for all four triangular sides equals 385. Hope that helps! :)

Answer:

Option A,
385.0\ ft^2

Explanation:

Step 1: Determine the area of the base


A = l * w


A = 11\ ft * 11\ ft


A = 121\ ft^2

Step 2: Determine the area of the triangles


A = (h * b)/(2)


A = (12\ ft * (11\ ft / 2))/(2)


A = (12\ ft * 5.5\ ft)/(2)


A = (66\ ft^2)/(2)


A = 33\ ft^2

There are two of these triangles per side which means that there are 8 of these triangles in total.


33\ ft^2 * 8


264\ ft^2

Step 3: Determine the surface area


SA = 121\ ft^2 + 264\ ft^2


SA = 385\ ft^2

Answer: Option A,
385.0\ ft^2
