Answer:
B) 1152 in2
Explanation:
Think about the surface area in sections: there is 4 triangles and 1 square
The equation to find the area of a triangle is A = (b x h)/2
b = base h = height
So, to find the area of one of the triangles, you would do:
(24 x 12)/2 = 144
Since the other three triangles are the same area, you only need to multiply what you found by 4 to get all of them.
144 x 4 = 576
Next, find the area of the square in the middle
The equation for a square is A = l x w
l = length and w = width
So to find this area, it is:
24 x 24 = 576
Finally, add the areas of the triangles and the square to find the total area:
576 + 576 = 1152
