Question

In the given figure area of ∥ gm PQRS is 30 cm². Find the height of ∥ gm PQFE if PQ = 6 cm.

Answer 1

Area(|| gm PQRS) = Area(|| gm PQFE)
(|| gm on same base PQ and between same parallel lines)
∴ Area(|| gm PQEF) = 30cm²
⇒ Base x HEight = 30
⇒ 6 x Height = 30

⇒ Height = `(30)/(6)` = 5cm
∴ The height of a parallelogram PQEF is 5cm.
