You can put this solution on YOUR website! First you should write out the word in equation form. Let l be the length of the rectangle and w be the width of the rectangle =). "The perimeter of a rectangle is 600": . I got this equation from knowing the defintion of perimeter: The perimeter of something is the length of all the sides. Now for the second secntence. "The length of the rectangle is 2 more than 3 times the width.": . If you plug into , you get . This becomes . Adding the w's together and subtracting 4 from both sides you get: . Divide both sides by 8 to get w=74.5. Then you can plug w=74.5 into equation or to get the value of l. I'll plug w=74.5 into to get . Then solving for l you get l=225.5. So the rectangle is 74.5 by 225.5! ^0^
