since a square sides are all equal in length. take the square root of 144 and you get 12
so if all all 4 sides of a square are 12 meters long, just add up all 4 sides
12+12+12+12=48
perimeter = 48
48 inches.
4.8 feet
Area = 9 sq inchesLength of side = sqrt(9) = 3 inchesPerimeter = 4*Length of side = 4*3 = 12 inches
24
If the area of a square is 81, then the length of a side is 9. Add up the length of all four sides to get the perimeter: 9 + 9 + 9 + 9
