Question

How much baseboard is needed to go around a rectangular room that measures `18` feet by `13` feet. If baseboard costs `$1.87` per foot, what is the total cost needed for materials?

Answer 1

The perimeter of a rectangle of length, `l`, and width, `w` is `2l+2w`. In this case, `2xx18+2xx13=36+26=62` feet.

The cost is `62xx$1.87=$115.94`
