Answer:
For a given length l and width w, the new perimeter is....
2(l + w) + 8
Step-by-step explanation:
Currently, the rectangle's perimeter is 2(l + w). You knew that.
Now, the question asked you to change l into l + 7, and w into w - 3. Substitute them, so we get
Perimeter New = 2(l + 7 w - 3) = 2 (l + w + 4)
Then, I chose to "pull out" + 4, so I multiply it with the 2. Hence, we get
Perimeter New = 2 (l + w) + 8
If you use the equation for interest, you get $493.50
