Answer
||gm ABCD and ||gm ABEF are on same base (AB) and between the same parallel lines AB and DE, so their areas are equal.
Area of ||gm ABEF = Area of ||gm ABCD = 29 cm2.
Area of ||gm ABEF = base × height
⇒ 29 = AB × height
⇒ 29 = 5.8 × height
⇒ Height =
= 5 cm.
The height of parallelogram ABEF is 5 cm.
