Question 954398
A rectangle has a length that is five times longer than its width. If the perimeter of the rectangle is 12 inches, what is the width?
--------
I got the equation 5w+w=12  and with that i added 5w+w and got 6w=12... After that i divided 6w and got 2... That was the wrong answer... My teacher said it was one and didnt explain how to get that answer... I am just confused... If you could help me it would be extremely appreciated..
Perimeter = 2W + 2L = 12
W + L = 6, not 12 --> your calculations would be 1.
===============
But, 5 times longer is not 5 times as long, it's 6 times.
W + 6W = 6
W = 6/7 inches
------------------
If 5 times longer = 5 times as long, what is 1 time longer?  --> a 100% increase = 2 times as long.
