Problem: A triangle has sides measuring 3.45 cm, 5.245 cm, and 6.5 cm. What is its perimeter?
Answer: [tex]\boxed{\bold{\green{15.195cm}}}[/tex]
Solution: To know the perimeter of the triangle use the formula [tex]\boxed{\rm{P \: = \: s + s + s}}[/tex], s means the sides of the triangle. The solution is you have to add all sides.
- [tex] \begin{gathered} \begin{gathered}\begin{gathered}\boxed{\begin{array}{l} \rm\red{\: \: \: \: \:\: \: \: \:Perimeter \: of \: a \: Triangle } \\ \\ \tt{P \: = \: s\: + \: s \: + \: s} \\ \tt{P \: = \: 3.45cm \: + \: 5.245cm \: + \: 6.5cm} \\ \tt{P \: = \: 8.695cm \: + \: 6.5cm} \\ \tt{P \: = \: 15.195cm} \\ \end{array}}\end{gathered} \end{gathered}\end{gathered} [/tex]
The perimeter of the triangle is 15.195cm.
