Answer:
2x + 8 = 38
Step-by-step explanation:
A rectangle has four sides, so we need to account for four sides. The length and the width are both the same measurement, so we end up getting:
x
x
4
4
Bam, four sides. Now we need our equation. We have two x's so we can say 2x since they are common terms. Now we can combine the two 4's since they are also two terms. Now our four sides looks like this:
2x
8
Now that we have it simplifed, we need to set up an equation. Since all the sides added together are equal to the perimeter, we can set up the following equation:
2x + 8 = 38
Hope this helps! Have a nice day :)
