Question

The ratio of two sides of a parallelogram is 4:3. If its perimeter is 56 cm. find the
lengths of its sides.
Let the lenthe fooides of the parallelogram he demand 3 cm respectively.​

Answer 1

Answer:

Step-by-step explanation:

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.  

Answer 2

Step-by-step explanation:

Let common multiple be x

Sides = 4x, 3x

Perimeter = 2(l+b)

56 cm = 2(4x + 3x)

56 cm = 2(7x)

56 cm = 14x

x = 56/14

x = 4 cm

Therefore length = 16 cm and breadth = 12 cm
