Answer:
a) 72 cm2 (centimeter square)
b) 9 cm2 (centimeter square)
c) 9 cm2 (centimeter square)
d) 54 cm2 (centimeter square)
Step-by-step explanation:
a) the area of the rectangle = Base x Height
= 12 x 6
= 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)
