3. A garden plot is to contain 200 sq. ft. If its length is to be twice its width, what should its dimensions be?
Let x be the Width and 2x be the Length.
x = Width
2x = Length
The area of the rectangle is L x W so
Now we got the value of the width which is 10 ft. We will substitute the value of x to the equation of the length.
20 ft. x 10 ft.
