Which equation can be used to calculate the area of the shaded triangle in the figure below? A rectangle with length of 18 feet and width of 6 feet. A diagonal cuts the rectangle into two halves. One of the triangular halves is shaded. (1 point) a 2(18 + 6) = 48 b fraction 1 over 2 (18 + 6) = 12 c fraction 1 over 2 (18 × 6) = 54 d 2(18 × 6) = 216
