Question

Two sides of a triangle are and 14 cm. The primeter of the triangle is 36cm. what is its third side .​

Answer 1

Step-by-step explanation:

Let the length of the third side be x cm.

The length of the other two sides is 12 cm and 14 cm.

Now, the Perimeter of triangle = 36 cm

12+14+x=36

26+x=36

x=36-26=10

Thus, the length of third side is 10 cm.

Answer 2

Answer:

Peri.eter of a triangle = side + side + side

Given from the question, it is an isoceles triangle as two sides are equal.

Therefore, 14 + 14 + length of third side = 36cm

Therefore, 28 + length of third side = 36

Therefore, length of third side = 36 - 28

= 8cm
