Question 716869
<font face="Times New Roman" size="+2">


The area is the length times the width.  FOIL the two binomials, set them equal to the given area, put the equation into standard form, and solve.  Discard the negative root because a negative length or width makes no sense.  The positive root will give you two positive dimensions when you calculate x + 1 and x - 3
