Question 1015401: The length of a rectangle is 3 ft less than twice it's width. If the perimeter of rectangle is 144 ft find the length and width Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! L= 2W-3
2(2W-3)+2W= 144
4W-6+2W= 144
4W+2W= 150
6W= 150
W= 150/6
W= 25 The width is 25, and the problem tells us that the length is:
2(25)-3= 50-3= 47 is the length
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check:
2(47)+2(25)= 144
94+50= 144 We have the correct answer
