Question

What are the dimensions of a rectangular tract of land when its perimeter is 66 kilometers and its area is 260 square kilometers? (enter the lengths of the sides as a comma-separated list.)?

Answer 1

the longer sides are 20 kilometers, and the shorter sides are 13 kilometers. 
(Length times width equals 260, and 20 times 2 plus 13 times 2 is 66.)
