P=2l+2w, so the perimeter is 21 yards.
A possibility: 2 yards by 3 yards
60 feet or 10 yards - without the aid of a calculator !
3 yards x 2 yards
Perimeter = 120+60+120+60 = 360 yards
328 yards or 984 feet.
A room that is 25.5 yards * 32 yards has a perimeter of 2*(25.5 + 32) = 2*57.5 = 115 yards. If each string of lights is 5 yards long, the number of strings required is 115/5 = 23.
161.5 feet.
10+10+10+10=40 yards
17+17+10+10=54 yards
270 feet.
420 yards.
