pls answer fast

Answer 1

Step-by-step explanation:

11x + 12x + 13x = 72

x = 36 = 72

x = 2 .

11 *2 ,12* 2, 13 *2

22 , 24 , 26

are the sides of triangle.

THANKS.

Answer 2

Before, we find the answer. Let's find out what we have to find in the answer.

• In this question, we are asked to find the sides of the triangle.

_____________________

Given :

• Ratio = 11:12:13
• Perimeter = 72cm

To find :

• the sides of the triangle

Steps :

• Let's add the ratios.
• Then, dividing with the perimeter.
• Now, multiplying them with x.

Solution :

⇒ Adding the ratios.

Let the side be "x"

11x + 12x + 13x = 72 cm

36x = 72 cm

      = 72/36

      = 2

⇒ Now, finding the sides.

• 11x = 11 × 2

             = 22 cm

• 12x = 12 × 2

              = 24 cm

• 13x = 13 × 2

              = 26 cm

Therefore, the sides of the triangle are 22 cm, 24 cm, and 26 cm.
