Question 1053895: A tract of land is rectangular, and the length is twice the width. The area in square miles is equal to the perimeter in miles. Determine dimensions.
Partial attempt:
Area = Length * Width
Perimeter = 2L + 2W
Length = 2W
Area = Perimeter
Unsure bow to continue. Thanks. Found 3 solutions by KMST, addingup, MathTherapy:Answer by KMST(5328) (Show Source):

Since is not zero, the equation simplifies to ,
meaning ,
and or .
So, the tract is 6 miles long and 3 miles wide.
That makes the perimeter 18 miles, and the area 18 square miles.
You can put this solution on YOUR website! You have done what can be done. You need more information. The length of a side for example.
:
W*2W = Area
2W+2(2W) = Perimeter

Width: W
Length: 2W
Area:
Perimeter: 2(W + 2W), or 2(3W), or 6W
Area = Perimeter, so:
You should be able to find the length.
