What is the typical width of panels that a builder uses to cover a wall if the wall is nine feet and it takes 12 panels to cover it?

• A. ½ foot
• B. ⅓ foot
• C. ¾ foot
• D. 1 foot

Answer: (C)

To determine the typical width of each panel, you can divide the total width of the wall by the number of panels used to cover that width. In this case, the wall is nine feet wide, and it requires twelve panels to cover it fully.

When you divide nine feet by twelve panels, the calculation is as follows:

9 feet ÷ 12 panels = 0.75 feet per panel.

Since 0.75 feet can also be expressed as ¾ of a foot, this confirms that the typical width of each panel is indeed ¾ foot. This answer makes sense within the context of the question, as it showcases a common panel width that builders might regularly use for wall coverings.

Other options reflect sizes that do not yield a full coverage of nine feet with twelve panels. For instance, using a width of ½ foot would only cover six feet with twelve panels, while 1 foot per panel would exceed the wall’s width, covering twelve feet instead of nine. Thus, ¾ foot is the only width that allows the total coverage to align perfectly with the wall size specified in the question.
