Answer :

One foot is 12 inches, so 5 1/2 feet are 66 inches.

There are 36 inches in a yard, so 36 inches is 1 yard and 6 yards is 216 inches.

There are three feet in a yard, so 90 feet will be 30 yards.
12 in= 1 ft ratio and proportion 1/12= x/5.5 cross multiply 66in= 5.5 ft 36= 1 yd 36/1= x/6 x= 210 inches 3/1= 90/x x= 30 yds hope this helps
