Find the perimiter now

that is right triangle so
when hpotonouse is c and hthe lgs are a and b
a²+b²=c²

given
leg is 8
hypotonuse is 13

8²+b²=13²
64+b²=169
minus 64 from both sides
b²=105
sqrt both sides
b=√105

find total perimiter
8+13+√105=21+√105

times 1/32 for scale
0.65625+0.32021721143623744947565745876628=
0.97646721143623744947565745876628 m=
97.646721143623744947565745876628 cm

A is the answer

Here, third side of actual sail, 
p² = h² - b²
p² = 13²- 8²
p = √169-64
p = √105

Perimeter = 8 + 13 + √105 = 21 + √105
p = 21 + 10.2469
p = 31.24

Now, model = 31.24/32 = 97.65 cm

In short, Your Answer would be Option A

Hope this helps!
