Answer:

333 ft^2

Explanation:

Surface area is the sum of all the areas of the shape.

First, the area of the square in the center is simply 9x9 = 81.

The area of a triangle is (bh)/2, where b = base, and h = height

In the triangle, 9 is the base, and 14 is the height:

(9x14)/2 = 63

There are four triangles of the same area:

63 x 4 = 252

252 + 81 = 333
