Question

In a parallelogram it is being given that base = 14 dm and height = 6.5 dm. Find its area in

(i) cm².
(ii) m².

Answer 1

(i) Base = 14 dm = (14 $\times$ 10) cm = 140 cm [since 1 dm = 10 cm]
Height = 6.5 dm = (6.5 $\times$ 10) cm = 65 cm

Area of the parallelogram = Base $\times$ Height
= 140 cm $\times$ 65 cm
= 9100 cm²

(ii) Base = 14 dm = (14 $\times$ 10) cm [since 1 dm = 10 cm and 100 cm = 1 m]
= 140 cm = 1.4 m
Height = 6.5 dm = (6.5 $\times$ 10) cm
= 65 cm = 0.65 m

∴ Area of the parallelogram = Base $\times$ Height
= 1.4 m $\times$ 0.65 m
= 0.91 m²
