Let's call the width
w and the length
l based on this, we can make two equations based on the first and second sentences in the problem.


w = l + 2


2l + 2w = 182


If we substitute
l + 2 for
w into the second equation, we can make the following:


2l + 2(l + 2) = 182

  • Substitute


2l + 2l + 4 = 182

  • Use the Distributive Property


4l + 4 = 182

  • Combine like terms


4l = 178

  • Subtract 4 from both sides


l = (178)/(4) = (89)/(2)

  • Divide both sides by 4 and simplify

Now, let's find
w:


w = l + 2 = (89)/(2) + 2 = (93)/(2)


The length of the rectangle is
\boxed{(89)/(2) \,\textrm{ft}} and the width of the rectangle is
\boxed{(93)/(2) \,\textrm{ft}}.
