Question

2 sides of triangle = 12cm,14 cm
perimeter of triangle = 36 cm
third side = ?
how to find the third side?​

Answer 1

Answer:

Let the length of third side be x cm.

Length of other two side are 12 cm and 14 cm.

Now, Perimeter of triangle = 36 cm.

⇒ 12 + 14 + x = 36.

⇒ 26 + x = 36.

⇒ x = 36 - 26.

⇒ x = 10 cm.

Thus, the length of third side is 10 cm
