Final answer:
To find the reasonable estimate for the number of square feet of the table, add up the lengths of the individual pieces. The total length is 15 1/2 ft.
Step-by-step explanation:
To find the reasonable estimate for the number of square feet, we need to add up the areas of the individual parts of the table. We have four pieces: 4 1/2 ft, 2 ft, 5 1/2 ft, and 3 1/2 ft. We can add these lengths together to find the total length of the table.
4 1/2 ft + 2 ft + 5 1/2 ft + 3 1/2 ft = 15 1/2 ft
Therefore, a reasonable estimate for the number of square feet is 15 1/2 square feet.
