Use the image to answer the question.
An illustration shows a triangular prism with length 7 feet, width 4 feet, and perpendicular height of the triangular face 3 feet.
What is the total surface area of the two triangular bases of this tent?
(1 point)
ft.2
The total surface area of the two triangular bases can be calculated using the formula for the area of a triangle: 1/2 * base * height.
For one of the triangular bases, the base is the width of the prism (4 feet) and the height is the perpendicular height of the triangular face (3 feet).
Area of one triangular base = 1/2 * 4 ft * 3 ft = 6 ft^2
Since there are two triangular bases, the total surface area of the two triangular bases is 2 * 6 ft^2 = 12 ft^2.
