Question 175404
Let's call the width of the rectangle w.  Then we can denote the length of the rectangle by w+5 since the length is 5 inches more than its width.  Remembering that the perimeter equation is 2*length + 2*width, we get that

{{{2w + 2(w+5) = 66}}}
So
{{{2w + 2w + 10 = 66}}}
Combining like terms and subtracting 10 yields
{{{4w = 56}}}
Dividing both sides by 4, we get
{{{w = 14}}}
So the width of the rectangle is 14 inches.  Using the knowledge we have about the length, that means the length is 19 inches.
