Question

problem 4 - part c
an equilateral triangle has three sides of equal length. function p gives the perimeter of an equilateral triangle of side length s.
find p(s).

Explanation:

Step1: Recall perimeter of triangle

Perimeter of a triangle is sum of all three sides.

Step2: Apply to equilateral triangle

An equilateral triangle has three equal sides, each of length \( s \). So perimeter \( P(s) = s + s + s \).

Step3: Simplify the expression

\( s + s + s = 3s \), so \( P(s) = 3s \).

Answer:

\( P(s) = 3s \)
