Answer:

$x^{2} + 22x + 120$

Step-by-step explanation:

The ball pit was originally 10 × 12 feet long, or a 120ft area.

We can express the areas of the side and bottom extensions as $12x$ and $10x$ respectively.

The corner adjacent to both extensions can be expressed as $x^{2}$.

We can put these numbers into a polynomial:

$x^{2} + 12x + 10x + 120$

This polynomial can then be simplified.

$x^{2} + 22x + 120$
