Which equation can be used to calculate the area of the shaded triangle in the figure below? A rectangle with length of 12 feet and width 4 feet. A diagonal cuts the rectangle into two halves. One of the triangular halves is shaded. (5 points) 2(12 + 4) = 32 fraction 1 over 2 (12 + 4) = 8 2(12 × 4) = 96 fraction 1 over 2 (12 × 4) = 24
