Hi

length is three inches more than it's width. 

Let x and (x+3)represent the width and length respectively

Question states***

If The length is incresed by one while the width stays the same, the area is increased by 13 square inches

 x(x+3)+13 = x(x+4)  this is the Set-Up

   13 = x, the width, original length is 16in
