( score points) point for correct answer point for complete support OR ½ point for correct but incomplete support What? Part C Answer Why? Sample Explanation: Since the area of the hole is the product of the width and the length, I can divide the area by the width to find the length, 9 = 4 }. That means the hole would be 4 } inches in length. However, the width of the entire metal plate is only } inches, so Pamela s calculation must be incorrect.
