1 answer

To find the area of the base of the figure, you would use the formula for the area of a triangle, since the base of the prism is a triangle. The formula for the area of a triangle is:

Area = 1/2 * base * height

In this case, the base of the triangle is 8 cm and the height of the triangle is 3 cm. Plugging these values into the formula:

Area = 1/2 * 8 cm * 3 cm
Area = 1/2 * 24 cm^2
Area = 12 cm^2

Therefore, the area of the base of the figure is 12 square centimeters.
