Question 149103
The perimeter of a rectangle is given by {{{P=2L + 2W}}} where {{{L}}} is the length and {{{W}}} is the width.  You are given that the length is 14 more than the width, so you can say {{{L=W+14}}}, and you are given that {{{P=264}}}.  So take the equation for the perimeter:


{{{P=2L + 2W}}} and substitute:


{{{264=2(W+14)+2W}}}


Now all you have to do is solve that equation for W to get the width, and add 14 to that answer to get the length.
