Question
Sides of a parallelogram are in the ratio 5:2. Its area
is 1000 sq. units. Altitude on the greater side is 10 units. Altitude on the smaller side is:Solution
Using formula, Area of parallelogram = l x h Let the sides of parallelogram be 5x and 2x. Base × Height = Area of parallelogram ⇒ 5x × 10 = 1000 ⇒ x = 1000/(10 x 5) = 20 ⇒ Sides = 100 and 40 units Therefore, 40 x h = 1000 ⇒ h = 1000/40 = 25 units
