Question

problem 4 - part a
an equilateral triangle has three sides of equal length. function p gives the perimeter of an equilateral triangle of side length s.
find p(2).

Explanation:

Step1: Define the perimeter function

For an equilateral triangle, perimeter \( P(s) = 3s \) (since all three sides are length \( s \)).

Step2: Substitute \( s = 2 \)

Substitute \( s = 2 \) into \( P(s) \): \( P(2)=3\times2 \)

Step3: Calculate the result

\( 3\times2 = 6 \)

Answer:

6
