Length of a Rectangle Problem

The video tutorial explains how to find the perimeter of a box in terms of its width, W. It begins by stating the problem and then introduces the formula for perimeter. The tutorial guides viewers through the process of substituting the length in terms of W and simplifying the expression to find the perimeter. The solution is explained step-by-step, ensuring clarity and understanding.

What is the formula for the perimeter of a rectangle?

• Perimeter = 2 * (length + width)

• Perimeter = length * width

• Perimeter = length + width

• Perimeter = 2 * length + width

How is the length of the box expressed in terms of its width?

• Length = 3 - 2W

• Length = 2W - 3

• Length = W - 3

• Length = 3W - 2

What does the phrase '3 inches less than twice its width' mean?

• Double the width and add 3

• Add 3 to the width and then double it

• Subtract 3 from the width and then double it

• Double the width and then subtract 3

What is the expression for the perimeter of the box in terms of W?

• 4W + 6

• 6W - 6

• 6W + 3

• 4W - 6

What is the first step in simplifying the expression for the perimeter?

• Distribute the 2 across the expression

• Combine like terms

• Subtract 3 from the width

• Add the width to the length
