Find the perimeter of a triangle with sides (m+2n), (3m+3n) and (2m-6n).

Dear Student,

We know that, Perimeter of triangle=Sum of all sidesGiven sides are m+2n, 3m+3n, and 2m-6n. So,Perimeter of triangle=m+2n+3m+3n+2m-6n                                   =m+3m+2m+2n+3n-6n                                   =6m-nPerimeter of triangle=6m-n
