15 yards x 4 sides = perimeter of 60 yards
12yards
If the area is 900 and it is square, then each side measure 30 yards. That means the perimeter is 30x4 or 120 yards.
9 yards
312/4 = 78 yards
Each side of the dog pen will be 3 yards. There are four sides. Therefore, the perimeter will be 3 x 4 = 12 yards.
A square that has an area of four square yards would be two square yards on a side. Thus, the perimeter of such a square would be a total of eight yards.
13.08 yards.
Perimeter = 4*4.8 = 19.2 yards
if one side of the square is 8 yards, then its 32 yards, or 96 ft.
Each side of the square is a quarter of the square's perimeter.
12 yards (4 sides x 3 = 12)
Hint: the perimeter of a square is the sum of its four sides, so each side is one-quarter of the perimeter...
