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.
Now, let's solve the system of equations using substitution:
The length of the rectangle is 5 inches.
Now, let's use this to solve for the width.
The width of the rectangle is 19 inches.
Let's check our work:
The results match, so our answer is correct.
The rectangle is 5 inches long by 19 inches wide.
