#### Answer

an alligator with body length of 6 feet has tail length of 5.4 feet.

#### Work Step by Step

Consider the proportional relation between the alligator’s tail length and the body length.
Because, the alligator with a body length of 4 feet has 3.6 feet tail length.
So, the alligator with a body length of 1 foot will have $\frac{3.6}{4}\ \text{feet}$ tail length.
This shows that the alligator with a body length of 6 feet has $\left( \frac{3.6}{4}\times 6 \right)\ \text{feet}$ tail length. It is solved as,
$\begin{align}
& T=\frac{3.6}{4}\times 6 \\
& =5.4\ \text{feet}
\end{align}$
Hence,an alligator with body length of 6 feet has tail length of 5.4 feet.
