Question

Two adjacent sides of a parallelogram are in the ratio 5 :7 if the perimeter of parallelogram is 72 cm, find the length of its sides ​

Answer 1

Answer:

x=6

Step-by-step explanation:

(L+B)=72

5x+7x=72

12x=72

x=72/12

x=6

Answer 2

Answer:

Question:-

1. Two adjacent sides of a parallelogram are in the ratio 5:7. If the perimeter of parallelogram is 72cm, find the length of its sides.

To find,

• The length of the side of an parallelogram

Given as,

• Perimeter = 72 cm
• Adjacent sides = 5:7

Let,

• Let the ratio 5:7 be as 5x and 7x

Solution:-

━☆ Perimeter = 72 cm

━☆ 72 cm = 5x + 5x + 7x + 7x

━☆  72 cm = 10x + 14x

━☆ 72cm = 24x

 ━☆ $\rm x = \frac{72}{24}$

━☆ x = 3

Answer ━☆ 5x = $\rm\bold 5 \times 3 ; 7x = 7 \times 3=21$
