The function $P(s) = 3s$ gives the perimeter of an equilateral triangle of side length $s$. a. We need to interpret the meaning of $P(s) = 60$ in this context. b. We need to find the value of $s$ that makes $P(s) = 60$ true.

1. Problem Description

The function $P(s) = 3s$ gives the perimeter of an equilateral triangle of side length $s$.

a. We need to interpret the meaning of $P(s) = 60$ in this context.

b. We need to find the value of $s$ that makes $P(s) = 60$ true.

2. Solution Steps

a. $P(s) = 60$ means that the perimeter of the equilateral triangle is

6

0.

b. We are given that $P(s) = 3s$. We are asked to find the value of $s$ for which $P(s) = 60$.

We can set up the equation $3s = 60$.

To solve for $s$, we divide both sides of the equation by 3:

$s = \frac{60}{3}$

$s = 20$

3. Final Answer

a. $P(s) = 60$ means that the perimeter of the equilateral triangle is

6

0. b. The value of $s$ that makes $P(s) = 60$ true is $s = 20$.
