Question

Two sides of a parallogram are in ratio 3:4 If its perimeter is 42 cm find the lengths of its sides.​

Answer 1

Answer:

Let the sides be 3x and 4x.

Then the perimeter of the parallelogram is 2(3x+4x)=2×7x=14x.

The given data implies that 42=14x ⇒ x=42/14=3.

Hence the sides of the parallelogram are 3×3=9 cm and 3×4=12 cm.

Answer 2

Answer:

Two sides of parallogram are in ratio

let 3=3x

4=4x

perimeter of is 42

3x+4x=42

7x=42

X=42/7

X= 6

3x=3×6

18

4x=4×6
