= 72 cm2 (centimeter square)

b) the area of the triangle A = 1/2 x Base x Height

= 1/2 x 3 x 6

= 9 cm2 (centimeter square)

c) the area of the triangle B = 1/2 x Base x Height

= 1/2 x 3 x 6

= 9 cm2 (centimeter square)

d) area of the parallelogram = area of the rectangle - area of triangle A - Area of triangle B

= 72 - 9 - 9

= 54 cm2 (centimeter square)
