let the lengths of two sides of the parallelogram be 4x cm and 3x cm respectively
⇒ its perimeter = 2(4x + 3x) cm = 8x + 6x = 14x cm.
∴ 14x = 56 ⇔ x = ⁵⁶/₁₄ = 4.
∴ one side = (4 × 4) cm = 16 cm and other side = (3 × 4) cm = 12 cm.
⇒ its perimeter = 2(4x + 3x) cm = 8x + 6x = 14x cm.
∴ 14x = 56 ⇔ x = ⁵⁶/₁₄ = 4.
∴ one side = (4 × 4) cm = 16 cm and other side = (3 × 4) cm = 12 cm.
