Question
Sides of a parallelogram are in the ratio 6:5. Its area
is 2700 sq. units. Altitude on the greater side is 30 units. Altitude on the smaller side is:ÂSolution
Using formula, Area of parallelogram = l x h Let the sides of parallelogram be 6x and 5x. Base × Height = Area of parallelogram ⇒ 6x × 30 = 2700    ⇒ x = 2700/(30 x 6) = 15 ⇒ Sides = 90 and 75 units Therefore, 75 x h = 2700 ⇒ h = 2700/75 = 36 units
