12yards
15 yards x 4 sides = perimeter of 60 yards
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
Each side of the dog pen will be 3 yards. There are four sides. Therefore, the perimeter will be 3 x 4 = 12 yards.
312/4 = 78 yards
Each side measures nine inches.
30 cm
Each side measures 18 meters.
Since a square has four sides:16 miles x 4 = 64 mile perimeter
44 cm
It is: 3*3*5 = 30 cubic yards
9 x 9 = 81cm2Therefore, each of the 4 sides of the square measures 9cm.The perimeter is: 9 x 4 = 36cm
