The widths of the tables are 5 feet 4 inches wide and 5 feet 9 Inches wide.
The first step is to add the dimensions in feet. We have
5 + 5 = 10 feet
The next step is to ad the dimensions in inches. We have
4 + 9 = 13 inches
Recall,
1 foot = 12 inches
Thus means that 13 inches = 1 foot and 1 inch. Adding 1 foot and 1 inch to 10 feet, the total width would be
11 feet 1 inch
