H&S Carpentry Practice Test

Question: 1 / 400

To calculate the square footage of a room, which mathematical operation is required?

Addition of length and width

Multiplication of length by width

To calculate the square footage of a room, you need to determine the area, which is done by multiplying the length by the width of the room. This operation provides the total space available within the boundaries defined by those dimensions.

While addition, division, or subtraction may be useful in other contexts, they do not yield the correct result for calculating area. Addition would combine dimensions but not provide an area measurement. Division might suggest a comparison of some sort, and subtraction would indicate a difference, neither of which applies to the straightforward calculation of square footage. Thus, the correct mathematical operation for finding the square footage is indeed the multiplication of length by width.
