Verified 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
