Two sides of a parallelogram are in the ratio 5 : 3. If its perimeter is 64 cm, find the lengths of its sides. |
|
Answer» Let x be the common multiple. According to question, sides will be 5x and 3x. Perimeter = \(2(l+w)\) 64 = 2 (5x + 3x) 64 = 16x x = 4 5x = 20 cm 3x = 12 cm So, sides will be 20 cm and 12 cm. |
