Answer:
The area of a rectangle is calculated by multiplying its length by its width. This can be written as:
Area = Length x Width
You know that the area of the sandbox is 17 square feet and the length is 3 feet. So, you can set up the equation like this:
17 = 3 x Width
To solve for the width, you need to divide both sides of the equation by 3:
Width = 17 / 3
So, the width of the sandbox is approximately 5.67 feet.
