Question 425637
Just add the side lengths. You will have to simplify the radicals though:


{{{2sqrt(8) + 5sqrt(18) + 3sqrt(50) + 5sqrt(75) = 4sqrt(2) + 15sqrt(2) + 15sqrt(2) + 25sqrt(3)}}} (I just factored out the largest square divisor out of each radical)


Collect like terms to obtain the perimeter, {{{34sqrt(2) + 25sqrt(3)}}}.
