Let's call the length of the rectangle, in yards,  L  .

Let's call the width of the rectangle, in yards,  W .

 

The perimeter of the rectangle is 596 yards, so....

 

L + L + W + W   =   596

                                         Let's solve this equation for  L . Comine like terms.

2L + 2W   =   596

                                         Subtract  2W  from both sides of the equation.

2L   =   596 - 2W

                                         Divide through by  2 .

L   =   298 - W

 

Its length is 2 yards less than 4 times its width, so...

 

L   =   4W - 2

                                   Since   L  =  298 - W   we can replace  L  with  298 - W .

298 - W   =   4W - 2

                                   Add  2  to both sides, and add  W  to both sides.

298 + 2   =   4W + W

                                   Combine like terms.

300   =   5W

                                   Divide both sides by  5 .

60   =   W

 

Now we can use this value for the width to find the length.

 

L   =   298 - W

 

L   =   298 - 60

 

L   =   238

 

So the width is 60 yards and the length is 238 yards.

L   =   4W - 2

                                   Since   L  =  298 - W   we can replace  L  with  298 - W .

298 - W   =   4W - 2

                                   Add  2  to both sides, and add  W  to both sides.

298 + 2   =   4W + W

                                   Combine like terms.

300   =   5W

                                   Divide both sides by  5 .

60   =   W

 

Now we can use this value for the width to find the length.

 

L   =   298 - W

 

L   =   298 - 60

 

L   =   238

 

So the width is 60 yards and the length is 238 yards.
