I attached a picture of what you are supposed to do.
There is a square and a rectangle you must first find the area of. We can find the width of the rectangle by subtracting 7 from 12. Once we have all the dimensions, then comes the math.
7 x 7 = 49
12 x 5 = 60
49 + 60 = 109
This is the surface area of the front face of the figure. Multiply this by 2 because there is another one on the back. Now we need to worry about the sides, top, and bottom.
The bottom and right side are both 5 x 12 = 60, which makes 120.
The two squares on top are 5 x 5 and 5 x 7
25 + 35 = 60.
The lower square on the left side is 7 x 5 = 35. The other square on the left side is 5 x 5 = 25.
If we add all these together, we get our answer.
218 + 120 + 60 + 35 + 25 = 458 ft ^2
The answer is B. Hope this helps you.
