We can begin by using algebra to represent the problem mathematically. Let's let "x" be the length of the breath in meters. Then, according to the problem, the length of the classroom is "x + 5" meters.
The perimeter of a rectangle is given by the formula: , where P is the perimeter, l is the length, and w is the width. Using this formula for our rectangle, we get:
The problem states that the perimeter is at most 90 meters, so we can write:
To solve for x, we'll start by subtracting 10 from both sides of the inequality:
Next, we'll divide both sides by 4:
Therefore, the highest value for the breath is 20 meters. We can write this as an inequality:
