Question

21. The ratio of two sides a parallelogram is 3:5, and its perimeter is 48 cm. Find the sides of the
parallelogram​

Answer 1

Answer:

let first = 3x

second= 5x

a/q

2(l+b)= 48

2(3x+5x)= 48

8x = 24

x = 3

ans..

first = 3 × 3

= 9

second = 5× 3

= 15

Answer 2

The opposite sides of a parallelogram are equal.

Let the common multiple be x

Therefore,

• 3x + 5x + 3x + 5x = 48
• 16x = 48
• $x = \frac{48}{16}$
• $x = 3$

The sides are -

• 3x = 3 × 3 = 9cm
• 5x = 5 × 3 = 15cm
