1. The width of a rectangle is one-third its length. if the area of the rectangle is 20 sq. in, what are the exact dimensions of the rectangle.

2. a rectangular garden measuring 10ft. by 15 ft. is to be surrounded on three sides by a uniform tile path. if 100 sq feet of tile is used how wide should the path be.
