Question 149613

The length of a top of a board is 6m greater than width. The area is 72m^2. Find the diminsions for width of board and length of board. 
------------------
Let width be "x" meters.
Then length is "x+6" meters.
----------------
Area = width*length = 72m^2
x(x+6) = 72
x^2+6x-72 = 0
(x+12)(x-6) = 0
Positive solution:
x = 6 meters (width)
x+6 = 12 meters (length)
