Question

Two sides of a triangle are 12 cm and 14 cm. The perimeter of the triangle is 36 cm. What is its third side?​

Answer 1

Answer:

Perimeter of a triangle = Sum of all 3 sides

Let the 3rd side be 'x'.

36 = 12 + 14 + x

36 = 26 + x

x = 10

Answer 2

Answer:

third side =10

Step-by-step explanation:

12 , 14

and perimeter

36=12+14+x

x= third side (assume)

so..

36=26+x

therfore,

x=10
