What is the surface area of the figure? (1 point)
height is 20ft
base length is 12ft
base width is 8ft
edge 1 is 8ft
slant is 15ft
edge 2 is 8ft
To find the surface area of the figure, we first need to find the area of the two triangles on the sides and the area of the rectangle on the bottom.
Area of the two triangles:
1/2 * base * height
1/2 * 8ft * 15ft = 60 ft^2 for each triangle
2 * 60 ft^2 = 120 ft^2 for both triangles
Area of the rectangle:
base length * base width
12ft * 8ft = 96 ft^2
Now, to find the total surface area, we add up the areas of the two triangles and the rectangle:
120 ft^2 + 96 ft^2 = 216 ft^2
Therefore, the surface area of the figure is 216 square feet.
