Question

problem 4 - part b
an equilateral triangle has three sides of equal length. function p gives the perimeter of an equilateral triangle of side length s.
find p(10).

Explanation:

Step1: Define the perimeter function

For an equilateral triangle, the perimeter \( P \) of a triangle with side length \( s \) is the sum of all three sides. Since all sides are equal, the formula for the perimeter is \( P(s)=3s \).

Step2: Substitute \( s = 10 \) into the function

Substitute \( s = 10 \) into \( P(s)=3s \), we get \( P(10)=3\times10 \).

Step3: Calculate the result

\( 3\times10 = 30 \).

Answer:

30
