To find the area of the table, you multiply its length by its width.

  1. First, let's convert the mixed numbers to improper fractions.
  • The length \( 4 \frac{1}{2} \): \[ 4 \frac{1}{2} = \frac{9}{2} \]

  • The width \( 2 \frac{1}{4} \): \[ 2 \frac{1}{4} = \frac{9}{4} \]

  1. Now, multiply these two fractions together to find the area: \[ \text{Area} = \text{Length} \times \text{Width} = \frac{9}{2} \times \frac{9}{4} \]

  2. Multiply the numerators and the denominators: \[ \text{Area} = \frac{9 \times 9}{2 \times 4} = \frac{81}{8} \]

  3. Now, convert \( \frac{81}{8} \) to a mixed number: \[ 81 \div 8 = 10 \text{ remainder } 1 \] So, \[ \frac{81}{8} = 10 \frac{1}{8} \]

Thus, the area of the table is \( \mathbf{10 \frac{1}{8}} \) square feet.

The correct response is:

  • 10 1/8 square feet.
