Answer:
16r - 14s
Step-by-step explanation:
The perimeter is a measure of a polygon that describes the distance around the boundaries of a shape.
Perimeter Formula
The perimeter of a rectangle is equal to [tex]l + l + w + w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width. This can be simplified to [tex]2l+2w[/tex]. Now, we can plug in the expression we are given for width and length.
- [tex]2(r-5s)+2(7r-2s)[/tex]
Simplifying the Expression
The expression above does accurately depict the perimeter, but it should be simplified to make the expression easier to understand and use.
First, distribute the 2 inside the parentheses.
The next step is to combine like terms. Like terms are terms that have the same power and variable. For example, 2r and 14r are like terms.
This is the simplified expression and the final answer.
