The given figure has a right triangle with lengths of sides 3 feet, 4 feet, 5 feet
Since the perimeter of any triangle is the sum of the lengths of its sides, then
The perimeter of the right triangle is
[tex]\begin{gathered} P=3+4+5 \\ P=12\text{ft} \end{gathered}[/tex]
Since the length of the longest side is 5 feet, then
The ratio of the longest side to the perimeter is
[tex]\frac{h}{P}=\frac{5}{12}[/tex]
The answer is 5/12 (5: 12)
