Question 1204760
<font color=black size=3>
w = width
w+4 = length


width*length = area
w*(w+4) = 12
w^2+4w = 12
w^2+4w-12 = 0


Use the quadratic formula to solve for w.
Or you can guess-and-check to factor.
Either way you should find that:
w = -6, w = 2
Ignore the negative value. A negative width is not possible.


If w = 2, then w+4 = 2+4 = 6
The rectangle is 2 inches by 6 inches.
