Question 118063
To find the perimeter, simply add up all of the sides. So the perimeter is {{{P=side1+side2+side3}}}





{{{sqrt(5)-sqrt(3)+4+sqrt(5)+sqrt(3)}}} Plug in {{{side1=sqrt(5)-sqrt(3)}}}, {{{side2=4}}}, {{{side3=sqrt(5)+sqrt(3)}}}



{{{(1+1)sqrt(5)+(1-1)sqrt(3)+4}}} Combine like terms.



{{{4+2*sqrt(5)}}} Simplify 


So the perimeter of the triangle is {{{4+2*sqrt(5)}}}
