the complete question in the attached figure we have that b=8 H=13 H²=a²+b²----------------- >13²=a²+8²-- > a²=169-64------------ >a=10.25 Perimeter in actual sail=8+13+10.25=31.25 meters scale factor=1/32 1 in the model -----------------------------32 in the actual X-------------------------------------------31.25 x=31.25/32=0.9765 meters---------------- > 97.65 cms
the answer is the perimeter of the sail
on the model boat is 97.65 cms
