Perimeter of a Triangle:
P=Side1%2BSide2%2BSide3

P=4%2B%28sqrt%285%29-sqrt%283%29%29%2B%28sqrt%285%29%2Bsqrt%283%29%29 Plug in the given info


P=4%2B%28sqrt%285%29%2Bsqrt%285%29%29%2B%28-sqrt%283%29%2Bsqrt%283%29%29 Group like terms

P=4%2B%28sqrt%285%29%2Bsqrt%285%29%29%2Bcross%28-sqrt%283%29%2Bsqrt%283%29%29 Notice these add to zero and cancel out


P=4%2B2sqrt%285%29 Combine like terms


So the perimeter is 4%2B2sqrt%285%29
