Formula Evaluation
Formulas are expressions where a sequence of letters, numbers or symbols have a determined meaning in given system.
Formulas are usually expressed as mathematical operations that connect one or more variables.
The perimeter of a triangle is the sum of the lengths of its sides. Being a,b, and c their sides, then the perimeter has the formula
[tex]P=a+b+c[/tex]
We are given the values of
[tex]a=13\ inches[/tex]
[tex]b=7.2\ inches[/tex]
[tex]c=3.7\ inches[/tex]
Thus the perimeter is
[tex]P=13\ inches+7.2\ inches+3.7\ inches[/tex]
[tex]\boxed{P=23.9\ inches}[/tex]
