Mr. Crow, the head groundskeeper at High Tech Middle School, mows the lawn along the side of the gym. The lawn is rectangular, and the length is $5$ feet more than twice the width. The perimeter of the lawn is $250$ feet.  

1. Use the 5-D Process to find the dimensions of the lawn.

   Hint (a):

   Define the dimensions of the lawn based on the information that is given and create an expression to solve for the perimeter.

   More Help (a):

   Now try values for $x$ and run trials to see if they correspond to the given perimeter.

   Trial 1	Define		Do	Decide
   	width $x$	length $5+2x$	Solve for total perimeter $2x+2\left(5+2x\right)=6x+10$	$250$ feet

2. Use the dimensions you calculated in part (a) to find the area of the lawn.

   Hint (b):

   The area of a rectangle is $\text{length}·\text{width}$.

   Answer (b):

   The area of the lawn is $3,400$ square feet.
