Question 208643: The length of a rectangle is 3 meters less than 5 times the width. The perimeter is 18 meters. Find the length and width. Answer by nyc_function(2741) (Show Source):
You can put this solution on YOUR website! Let length = 5x - 3
Let width = x
The perimeter is 18
Use the formula: P = 2L + 2W as step one.
Here is the set up:
18 = 2(5x - 3) + 2(x)
When you find x, this will be your width. Then go back to 5x - 3, plug your value for x and simplify to find your length.
