Question
Sides of a parallelogram are in the ratio 7:5. Its area
is 735 sq. units. Altitude on the greater side is 35 units. Altitude on the smaller side is:Solution
Using formula, Area of parallelogram = l x h Let the sides of parallelogram be 7x and 5x. Base × Height = Area of parallelogram ⇒ 7x × 35 = 735 ⇒ x = 735/(35 x 7) = 3 ⇒ Sides = 21 and 15 units Therefore, 15 x h = 735 ⇒ h = 735/15 = 49 units
