For a rectangle, if x is the length and 2x is the width. Then find out x from the area of the rectangle?
if the area is equal to 200 then the length of the rectangle is 10.
Usually, if the dimensions of a rectangle are x and 2*x, then 2*x would be called its 'length', and x would be called its 'width'.
