So we see the pythagorean theorem a^2+b^2=c^2 diagonal=c width=a or b, pick one width=a legnth=b width is 5 times more than 2 times legnth of garden w=5(2legnth) this doesn't make sense since the legnth is normally longer than the width, but we'll stick with that w=5(2l) w=10l a=10b (10b)^2+b^2=90^2 100b^2+b^2=8100 101b^2=8100 divide by 101 b^2=80.198 aprox 80.2 square root 8.95533 legnth of garden =8.96 to find width subsitue w=10l w=89.56
