Let the length be 3x+2 and the width be x:
(3x+2)*x = 33
3x2+2x = 33
3x2+2x-33 = 0
Solve as a quadratic equation:
(3x+11)(x-3) = 0
Therefore: x = -11/3 or x = 3 The dimensions can't be negative so x must = 3
So: length = 11 feet and width = 3 feet

What is an expression for the perimeter of a rectangle that has a length which is three times its width?
call width x so length is 3x perimeter is (2*length)+(2*width) so perimeter is 8x
The length of a rectangle is three times its width If the perimeter of the rectangle is 48?
The perimeter of a rectangle is equal to 2*length + 2* width. In this case, we will say 2x + 2y = p = 48. Since the length is equal to 3 times the width, the equation now becomes p = 6*y + 2*y, or just p = 8y. Now since p =48, y must equal 6. And since the length is three times the width (y), the length is 18.

What are the length and width of a rectangle if the length is three times longer than the width the area is 48 sq cm?
Let x be the width of the rectangle. Then the length is 3x. The area of the rectangle is 3x * x = 3x^2, which also has to be 48. Solving for x, we get that the width is 4, and the length is 12.
