Question

what is the perimeter of triangle if it's two sides are X and third side is y​

Answer 1

Answer:

2x+y

Step-by-step explanation:

p of triangle=a+b+c

a=x

b=y

c=y

therefore

p of triangle=x+x+y

Answer 2

Perimeter of ∆ = side +side + side

=>Perimeter of ∆ = x+x+y

=> Perimeter of ∆ = 2x+y
