Answer:
10 feet is the width. (5on each side)
Step-by-step explanation:
If you multiply 5.25x2=10.5 then you subtract the perimeter 20.5-10.5= 10ft

Perimeter is the sum of the length of the sides used to make the given figure. The width of their sandbox is 5 feet.
Perimeter is the sum of the length of the sides used to make the given figure. The perimeter of the rectangle is two times the sum of the length and the width of the rectangle.
Therefore, the perimeter of the rectangle is written as,
The perimeter of the rectangle = 2 × (Length + Width)
Given that the length of a sandbox is 5.25 feet. Also, the perimeter of the sandbox is 20.5 feet. Therefore, the perimeter of the sandbox can be written as,
Perimeter of the sandbox = 2 × (Length + Width)
20.5 feet = 2 × (5.25 feet + Width)
20.5 feet/ 2 = (5.25 feet + Width)
10.25 feet = (5.25 feet + Width)
10.25 feet - 5.25 feet = Width
Width = 5 feet
Hence, the width of their sandbox is 5 feet.
