Question

how is the square footage of any building area determined?
divide length by width
multiply length by width
add length to width
subtract length from width and multiply by 4

Explanation:

The formula for the area of a rectangle (which can represent a building - shaped as a rectangle) is \(A = l\times w\), where \(l\) is the length and \(w\) is the width. Square footage is a measure of area. So, to find the square footage of a rectangular - shaped building area, we multiply the length by the width.

Answer:

B. multiply length by width
