Answer:
44 feet
Explanation:
1) Area of square = Length x Breadth (BOTH Length and Breadth have to be the same value)
2) Since the area of the sandbox is 121 square feet, find the square root of 121 to find the values of the length/breadth.
√121 square foot = 11 feet
3) The total length of the sandbox (perimeter) is:
(2 x Length) + (2 x Breadth)
= (2 x 11 feet) + (2 x 11 feet)
= 44 feet.
