Question

In figure, area (∆BCE) = 75.2 m². Find the area of parallelogram ABCD.

Answer 1

If a triangle and a parallelogram are on the same base and between the same parallels, then the area of triangle is equal to half the area of parallelogram.

i.e Area of ∆BCE = ar (||gm ABCD) 

⇒ 75.2 m² = ar(||gm ABCD) 

⇒ ar (||gm ABCD) = 75.2 x 2 m² 

= 150.4 m² .
