Answer:
Step-by-step explanation:
Let x = length
Then width = (1/2)x
Perimeter = 2(length) + 2(width) = 54
length + width = 27
So, x + (1/2)x = 27
(3/2)x = 27
x = 27(2/3) = 18 (1/2)x = 9
Answer: length = 18 cm and width = 9 cm
Using simple interest, it is found that the maturity value of the loan is of 10,638.
<h3>Simple Interest</h3>
The amount of money after <em>t years </em>in simple interest is modeled by:

In which:
- A(0) is the initial amount.
- r is the interest rate, as a decimal.
In this problem:
- A loan of 10450 is taken, hence
.
- Interest rate of 8.25%, hence

- The loan will be repaid in 75 days, considering the time in years,

Then, the maturity value of the loan is:

![A\left(\frac{75}{365}\right) = 10450\left[1 + 0.0875\frac{75}{365}\right] = 10638](https://tex.z-dn.net/?f=A%5Cleft%28%5Cfrac%7B75%7D%7B365%7D%5Cright%29%20%3D%2010450%5Cleft%5B1%20%2B%200.0875%5Cfrac%7B75%7D%7B365%7D%5Cright%5D%20%3D%2010638)
The maturity value of the loan is of 10,638.
