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

$P=a+b+c$

We are given the values of

$a=13\ inches$

$b=7.2\ inches$

$c=3.7\ inches$

Thus the perimeter is

$P=13\ inches+7.2\ inches+3.7\ inches$

$\boxed{P=23.9\ inches}$
