Question
Sides of a parallelogram are in the ratio 7:4. Its area
is 1176 sq. units. Altitude on the greater side is 28 units. Altitude on the smaller side is:Solution
Using formula, Area of parallelogram = l x h Let the sides of parallelogram be 7x and 4x. Base × Height = Area of parallelogram ⇒ 7x × 28 = 1176 ⇒ x = 1176/(28 x 7) = 6 ⇒ Sides = 42 and 24 units Therefore, 24 x h = 1176 ⇒ h = 1176/24 = 49 units
