so we will call the shorter side s and longer side is 2s+2 . Hypothenuse is 13
using the pathagorean theorem s%5E2%2B%282s%2B2%29%5E2=13%5E2 multiplied out we get 5s2+8x-165=0
factoring we get (5s+33)(s-5)=0 so s=5 and -33/5 throw out the negative value and s=5 meaning short side is 5 and longer side is 2(5)+2=12
