To solve this problem, we can follow these steps based on the given conditions:

Let:
- \( x \) be the length of the shorter leg of the right triangle.
- The longer leg is \( x + 3 \) feet (since it is 3 feet longer than the shorter leg).
- The hypotenuse is \( x + 6 \) feet (since it is 6 feet longer than the shorter leg).

Since this is a right triangle, we can use the **Pythagorean theorem**:

\[
\text{(shorter leg)}^2 + \text{(longer leg)}^2 = \text{(hypotenuse)}^2
\]

Substituting the values:

\[
x^2 + (x + 3)^2 = (x + 6)^2
\]

Now, let's solve this equation to find \( x \).

\[
x^2 + (x^2 + 6x + 9) = (x^2 + 12x + 36)
\]

Simplifying:

\[
2x^2 + 6x + 9 = x^2 + 12x + 36
\]

Move all terms to one side of the equation:

\[
2x^2 + 6x + 9 - x^2 - 12x - 36 = 0
\]

Simplify further:

\[
x^2 - 6x - 27 = 0
\]

Now, solve this quadratic equation using the quadratic formula:

\[
x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(1)(-27)}}{2(1)}
\]

\[
x = \frac{6 \pm \sqrt{36 + 108}}{2}
\]

\[
x = \frac{6 \pm \sqrt{144}}{2}
\]

\[
x = \frac{6 \pm 12}{2}
\]

So, we get two possible solutions:

\[
x = \frac{6 + 12}{2} = 9 \quad \text{or} \quad x = \frac{6 - 12}{2} = -3
\]

Since the length cannot be negative, the shorter leg \( x = 9 \) feet.

Thus:
- The shorter leg is \( 9 \) feet.
- The longer leg is \( 9 + 3 = 12 \) feet.
- The hypotenuse is \( 9 + 6 = 15 \) feet.

### Final answer:
- Length of the shorter leg: 9 feet
- Length of the longer leg: 12 feet
- Length of the hypotenuse: 15 feet
