A garden has an area of 288 ft squared. Its length is 2 ft more than its width. What are the dimensions of the​ garden?

Let the width of the garden be denoted by \( w \) feet. According to the problem, the length of the garden is 2 feet more than the width, so the length is \( w + 2 \) feet.

The area of a rectangle is given by:

\[
\text{Area} = \text{length} \times \text{width}
\]

Substituting the given values:

\[
288 = w \times (w + 2)
\]

This expands to the quadratic equation:

\[
288 = w^2 + 2w
\]

Rearranging the equation:

\[
w^2 + 2w - 288 = 0
\]

Now, solve this quadratic equation using the quadratic formula:

\[
w = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
\]

where \( a = 1 \), \( b = 2 \), and \( c = -288 \). Substituting these values:

\[
w = \frac{-2 \pm \sqrt{2^2 - 4(1)(-288)}}{2(1)}
\]
\[
w = \frac{-2 \pm \sqrt{4 + 1152}}{2}
\]
\[
w = \frac{-2 \pm \sqrt{1156}}{2}
\]
\[
w = \frac{-2 \pm 34}{2}
\]

Thus, the two possible solutions for \( w \) are:

\[
w = \frac{-2 + 34}{2} = \frac{32}{2} = 16
\]
or
\[
w = \frac{-2 - 34}{2} = \frac{-36}{2} = -18
\]

Since the width cannot be negative, we have \( w = 16 \) feet.

Therefore, the width is 16 feet, and the length is:

\[
\text{length} = w + 2 = 16 + 2 = 18 \, \text{feet}.
\]

Thus, the dimensions of the garden are:

\[
\text{Length} = 18 \, \text{feet}, \quad \text{Width} = 16 \, \text{feet}.
\]
