Question

The ratio between the adjacent sides of a
parallelogram is 3.5. The perimeter of the
parallelogram is 144 cm. Find the lengths of the
sides of parallelogram




please give me a right answer ​

Answer 1

Answer:

using formula = 2( side 1 + side2)

we get

2(3x+5x)=144

2(8x)=144

8x=72

x=9

hence in parallelogram adjacent sides are equal therefore

1 length = 27

2 length= 45

Answer 2

Answer:

The sides of parallelogram are 27 cm and 45 cm

Step-by-step explanation:

Given:

• The ratio between the adjacent sides of a

• parallelogram is 3 : 5

• The perimeter of the parallelogram is 144 cm

To find :

• The measure of the sides of parallelogram

Solution :

Let,

The adjacent sides of a parallelogram =

• 3x
• 5x

As we know ,

★ Perimeter of parallelogram : 2 (sum of the adjacent sides)

So,

⇒ 2 (3x + 5x) = 144

⇒ 2 (8x) = 144

⇒ 16x = 144

⇒ x = 144 / 16

⇒ x = 9

★ Value of 3x :

⇒ 3 (9)

⇒ 27

★ Value of 5x :

⇒ 5 (9)

⇒ 45

Therefore,

The sides of parallelogram are 27 cm and 45 cm
