The question is , the length of a rectangle is twice the width.
Draw the rectangle.
Label the width as x and the length as 2x.
Then the area = x*2x = 2x^2
-------------------------------------------------
Equation:
The area is 648sqrt. find the length and the width.
Area = length*width
Area = 2x*x = 2x^2
648 = 2x^2
324 = x^2
x = 18 (that is the width)
2x = 36 (that is the length)
.
-------------------------------
