The perimeter of a triangle with sides of integer values is equal to 13. How many such triangles are possible?

Given: ​

Perimeter of Triangle is equal to integer 13 

Perimeter of a triangle = Sum of three sides of triangle

let the sides of triangle be a , b, c.

Then,

Perimeter = 13

a + b + c = 13 

So, possible integer values be 
1 + 6 + 6
2 + 5 + 6
3 + 5 + 5
4 + 4 + 5
6 + 4 + 3
Therefore, 5 triangles are possible​​
