perimeter = 2L +2W
the problem states the length ( L) is 2 meters longer then width, so L = w+2
so perimeter =2(w+2) +2w
24 = 2(w+2) +2w
24 = 2w+4 +2w
24 = 4w+4
20=4w
w=20/4 = 5
Answer:
The principal is $2400
Step-by-step explanation:
Given

![t = 9](https://tex.z-dn.net/?f=t%20%3D%209)
![r =12\%](https://tex.z-dn.net/?f=r%20%3D12%5C%25)
![I = \$25920](https://tex.z-dn.net/?f=I%20%3D%20%5C%2425920)
Required
