Translating our series to the short form:

plugin in the values for the 12 month gives:

So given l = x+5 and w = x
area represented by equation x^2 +5x = 300
x^2 +5x -300 =0
(x+20)(x-15)=0
x+20 =0
x = -20
x-15=0
x=15
so from these result the width of rectangle equal 15 inches and the length of rectangle equal 20 inches
