Problem
22) What is the formula for finding the perimeter of this hexagon? 23) Find the perimeter, when \( s=10 \mathrm{~mm} \). 24) Find the perimeter, when \( s=8 \mathrm{~km} \). 5) What is the length of each side of a regular hexagon when the perimeter is \( 72 \mathrm{~m} \) ?
Solution
Step 1 ：\( P = 6s \)
Step 2 ：\( P = 6(10 \mathrm{~mm}) = 60 \mathrm{~mm} \)
Step 3 ：\( P = 6(8 \mathrm{~km}) = 48 \mathrm{~km} \)
Step 4 ：\( s = \frac{P}{6} = \frac{72 \mathrm{~m}}{6} = 12 \mathrm{~m} \)
