Answer:

see explanation

Explanation:

(a)

area of rectangle = lb ( l = 12 , b = 6 )

area = 12 × 6 = 72 cm²

(b)

area Δ A =
(1)/(2) bh ( b = 3 , h = 6 )

area =
(1)/(2) × 3 × 6 =
(1)/(2) × 18 = 9 cm²

(c)

area Δ B =
(1)/(2) bh ( b = 3, h = 6 )

area =
(1)/(2) × 3 × 6 = 9 cm²

(d)

area of parallelogram = area of rectangle - area Δ A - area Δ B

= 72 - 9 - 9

= 72 - 18

= 54 cm²
