Final answer:
The equation that can be used to find the length and width of the sandbox is 2w + 2(w + 3) = 62. By solving this equation, we can determine that the width of the sandbox is 14 feet and the length is 17 feet.
Step-by-step explanation:
To find the length and width of the sandbox, we can use the equation 2w + 2(w + 3) = 62. Let's break it down step by step:
- Let w represent the width of the sandbox.
- The length of the sandbox is 3 feet longer than the width, so the length can be represented as w + 3.
- The perimeter of a rectangle is found by adding the lengths of all four sides, so we have 2w + 2(w + 3) = 62.
- Simplify the equation: 2w + 2w + 6 = 62.
- Combine like terms: 4w + 6 = 62.
- Subtract 6 from both sides: 4w = 56.
- Divide both sides by 4: w = 14.
Therefore, the width of the sandbox is 14 feet, and the length is 14 + 3 = 17 feet.
