A rectangular flat screen TV has an area of 1200 square inches. If the longer side is two inches longer than twice the shorter side, find the dimaensions(length and height) of this flat screen TV.

Let the short side be x inches long.

Then the long side is 2x + 2 inches long.
Now make an equation using the area formula for a rectangle:
L * W = A
(2x + 2)*x = 1200
And solve for x.
(Remember x is the short side length; you can now use this to find the length of the long side)
