Question 1084067
Daniel is adding a metal border to a company's lawn to stop the grass growth. The length of the lawn is 42 yards and the width is 27 yards. 
--------------
Depends on the width of the border, W
The outside dimensions are 42 + 2W and 27 + 2W
Subtract the inner rectangle, 42*27.
-----
Area = (42+2W)*(27+2W) - 42*27
