Answer 2

Given:

• Two sides of the traingle are 12 and 14 cm.
• Perimeter of traingle = 36 cm

To Find:

• Third side of traingle.

Solution:

Perimeter of traingle = 36 cm

Let third side of traingle be x cm

➞ 12 + 14 + x = 36 cm

➞ 26 + x = 36

➞ x = 36 - 26

➞ x = 10 cm

Hence,

• Third side of traingle is 10 cm.

Verification:

Perimeter of traingle = 36 cm

➞ 12 + 14 + x = 36

➞ 12 + 14 + 10 = 36

➞ 26 + 10 = 36

➞ 36 = 36 cm

• Hence, verified
