Question

The area of parallelogram ABCD is 36cm² . Calculate the height of parallelogram ABEF if AB = 4.2 cm.

Answer 1

Area of □ABCD = 36 cm² 

AB = 4.2 cm 

then □ABCD = AB X Height 

[ ∵ base x height]

36 = 4.2 x h

∴ h = 36/4.2

But □ ABCD and □ ABEF are on the same base and between the same parallels. 

∴ □ABCD = □ABEF

□ABEF = base x height = AB x height

∴ height = 36/4.2 = 8.571cm
