To determine which area has a rational number as the side length, we need to find the perfect squares among the given areas.

First, let's find the square roots of each area to see if they are rational numbers:

- The square root of 144 is 12, which is a rational number.
- The square root of 32 is approximately 5.656854, which is an irrational number.
- The square root of 72 is approximately 8.485281, which is an irrational number.
- The square root of 250 is approximately 15.811388, which is an irrational number.

Therefore, the only area with a rational number as the side length is 144.
