3.8q + 21.2 + 8.3r
The perimeter is all sides added together, therefore our equation looks like this:
[tex](1.7q + 9.3) + (2.1q + 6.7) + (8.3r + 5.2)[/tex]
However, we can get rid of the parentheses and add like terms together.
[tex]1.7q + 9.3+ 2.1q + 6.7+ 8.3r + 5.2[/tex]
[tex]1.7q + 2.1q + 9.3 + 6.7+ 5.2 + 8.3r [/tex]
[tex] 3.8q + 21.2 + 8.3r [/tex]
