How do you calculate a perimeter? Write it as an inequality with the given restriction.
Inequality: 14.2+15.5+x<51.3 Solution: x<21.6
Practice makes perfect
We are asked to find the possible values of x which is the missing side length of the given triangle. Let's take a look at the given figure.
We will first find the perimeter by adding the three sides of the given triangle.
Perimeter=14.2+15.5+x
We are also given that the perimeter is less than 51.3 inches.
Perimeter< 51.3
By substituting the expression for the perimeter we formed above, we can form an inequality.
14.2+15.5+x< 51.3
Let's now solve this inequality by isolating x.
