Answer:
The rectangle is 5 inches long by 19 inches wide.
Step-by-step explanation:
Let's start by listing what we know:
- The perimeter of a rectangle is 48 inches.
- The width of the rectangle is 4 inches more than 3 times the length of the rectangle.
Let's represent the width with "w" and length with "l", and make a system of equations based on what we know.
![\left \{ {{2w + 2l = 48} \atop {w = 3l + 4}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B2w%20%2B%202l%20%3D%2048%7D%20%5Catop%20%7Bw%20%3D%203l%20%2B%204%7D%7D%20%5Cright.)
Now, let's solve the system of equations using substitution:
![2w + 2l = 48](https://tex.z-dn.net/?f=2w%20%2B%202l%20%3D%2048)
![2 (3l + 4) + 2l = 48](https://tex.z-dn.net/?f=2%20%283l%20%2B%204%29%20%2B%202l%20%3D%2048)
![6l + 8 + 2l = 48](https://tex.z-dn.net/?f=6l%20%2B%208%20%2B%202l%20%3D%2048)
![8l + 8 = 48](https://tex.z-dn.net/?f=8l%20%2B%208%20%3D%2048)
![8l = 40](https://tex.z-dn.net/?f=8l%20%3D%2040)
![l = 5](https://tex.z-dn.net/?f=l%20%3D%205)
The length of the rectangle is 5 inches.
Now, let's use this to solve for the width.
![w = 3l + 4](https://tex.z-dn.net/?f=w%20%3D%203l%20%2B%204)
![w = 3(5) + 4](https://tex.z-dn.net/?f=w%20%3D%203%285%29%20%2B%204)
![w = 15 + 4](https://tex.z-dn.net/?f=w%20%3D%2015%20%2B%204)
![w = 19](https://tex.z-dn.net/?f=w%20%3D%2019)
The width of the rectangle is 19 inches.
Let's check our work:
![2w + 2l = 48](https://tex.z-dn.net/?f=2w%20%2B%202l%20%3D%2048)
![2(19) + 2(5) = 48](https://tex.z-dn.net/?f=2%2819%29%20%2B%202%285%29%20%3D%2048)
![38 + 10 = 48](https://tex.z-dn.net/?f=38%20%2B%2010%20%3D%2048)
![48 = 48](https://tex.z-dn.net/?f=48%20%3D%2048)
The results match, so our answer is correct.
The rectangle is 5 inches long by 19 inches wide.
