The length of a rectangle is 3 times the side of a square. The width of the rectangle is 5 inches greater than the side of the square. If the area of the square is 4x^2 - 12x + 9 square inches, what are the dimensions of the rectangle?
Since the area of the square is given, we can factor and tell that each side of the square is equal to 2x - 3. Then we can make the changes identified to find the sides of the rectangle.
