So we start by converting each unit to feet (you could convert to any unit as long as they’re the same, but I’m going to show u how to find out with feet conversion)
1 feet = 12 inches, so to convert Xaviers fence from inch to feet we divide
62 ÷ 12 = 5.2 feet long.
Since Barry’s fence is already in feet, we know it’s 7 feet long.
Thomas’s feet which is 2 yards will be converted to feet as well.
1 yard= 3 feet, so 2 x 3 = 6 feet long
Xavier: 5.2 feet
Barry: 7 feet
Thomas: 6 feet
Therefore, choice b. Barry (7 feet) is the longest fence.
