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 found by adding the area of each triangular base.
The formula for the area of a triangle is 1/2 * base * height.
For the first triangular base:
Area = 1/2 * 4 feet * 3 feet = 6 square feet
For the second triangular base:
Area = 1/2 * 4 feet * 3 feet = 6 square feet
Adding the areas of both triangular bases:
Total surface area = 6 square feet + 6 square feet = 12 square feet
Therefore, the total surface area of the two triangular bases of this tent is 12 square feet.
