Question

the ratio of the sides of a parallelogram is 2:3 and its perimeter is 30 cm find the measure of the sides

Answer 1

$\bold{Answer:}$

Two sides are in ratio = 2:3,

Sides can be represented a 2x and 3x,

Perimeter = 2(2x)+2(3x),

Perimeter = 30 cm,

2(2x)+2(3x)=30,

4x+6x=30,

10x=30,

x=$\bold{\frac{30}{10} }$,

x= 3.

So, sides :

2x = 2(3) = 6 cm ,

3x = 3(3)= 9 cm.

Answer 2

Step-by-step explanation:

Two sides are in ratio = 2:3,

Sides can be represented a 2x and 3x,

Perimeter = 2(2x)+2(3x),

Perimeter = 30 cm,

2(2x)+2(3x)=30,

4x+6x=30,

10x=30,

x=\bold{\frac{30}{10} }

10

30

,

x= 3.

So, sides :

2x = 2(3) = 6 cm ,

3x = 3(3)= 9 cm.
