To find the perimeter, simply add up all of the sides. So the perimeter is P=side1%2Bside2%2Bside3




sqrt%285%29-sqrt%283%29%2B4%2Bsqrt%285%29%2Bsqrt%283%29 Plug in side1=sqrt%285%29-sqrt%283%29, side2=4, side3=sqrt%285%29%2Bsqrt%283%29


%281%2B1%29sqrt%285%29%2B%281-1%29sqrt%283%29%2B4 Combine like terms.


4%2B2%2Asqrt%285%29 Simplify

So the perimeter of the triangle is 4%2B2%2Asqrt%285%29
