Arectangular swimming pool measures 14 feet by 30 feet. the pool is surrounded on all four sides by a path that is 3 feet wide. if the cost to resurface the path is $2 per square foot, what is the total cost of resurfacing the path?

Using the formula for the area of the rectangle, and proportions, it is found that the total cost of resurfacing the path is $600.

-----------

The area of a rectangle of length l and width w is given by:

-----------

The area of the path will be the total area(pool + path), subtracted by the area of the pool.

-----------

-----------

-----------

-----------

Thus, the total cost is of: $2*300 = $600.
