Question

what is the perimeter of a triangle with side lengths of 11 meters, 15 meters, and 18 meters?
you do not need to include the unit measurement or unit type. only the numerical answer is necessary. round to the nearest tenth if necessary.

Explanation:

Step1: Recall the formula for perimeter

The perimeter \(P\) of a triangle is \(P=a + b+ c\), where \(a\), \(b\), and \(c\) are the side - lengths.

Step2: Substitute the values

Here, \(a = 11\), \(b = 15\), and \(c = 18\). So \(P=11 + 15+18\).

Step3: Calculate the sum

\(11+15 = 26\), and \(26+18=44\).

Answer:

44
