It would take about 21 foot rulers.
12 of them.
10-ft by 10-ft = 100 square feet = 111/9 square yards.
Ten yards.
There are 1760 yards in a mile
the answer is 40 square yards
It takes 4 yards to make 12 feet.
12 of them because 12 feet = 4 yards
14080 of them.
1093.61
15 of them because 15 feet = 5 yards
I think 17 or maybe 38
