Question 65687
Find the perimeter of the triangle:
I will try to draw out the triangle for you:
                    4
             ========================
             =                      =
             =                    =
sqrt5-sqrt3  =                 =
             =               =
             =             =
             =           =    sqrt5 + sqrt3
             =         =
             =       =
             =     =
             =   =
             =  =
             = =

To find the perimeter of any polygon, add all the sides togather:
{{{P=(4)+(sqrt(5)-sqrt(3))+(sqrt(5)+sqrt(3))}}}
{{{P=4+sqrt(5)+sqrt(5)-sqrt(3)+sqrt(3)}}}
{{{highlight(P=4+2*sqrt(5))}}}
