A rectangle is a geometric shape that is a type of quadrilateral. This four-sided polygon has four angles, with each equaling 90 degrees. You may be required to find the area or width of a rectangle as an assignment in a math or geometry class. Knowing h
You want "closest" length and width but do not explain how YOU define "closest". For example if you have length & width of a rectangle 2 ways of comparing them could be perimeter or area or something like delta length + delta width or you may want to square those differences (like var...
