Question

Which equation can be used to calculate the area of the shaded triangle in the figure below?

(7 points)


2(12 × 4) = 96 square feet


(12 × 4) = 24 square feet


2(12 + 4) = 32 square feet


(4 + 12) = 8 square feet

Answer 1

(12 × 4) = 24 square feet

Explanation:

The shaded triangle's area is found using the formula for the area of any triangle, A = 1/2 b*h. The base of the triangle is the longest side 12 ft. The height is 4 ft.

A = 1/2 *12*4 = 6*4 = 24 square feet

This is the solution though the expression is missing the 1/2.

(12 × 4) = 24 square feet
