Dimensions:

Width: x
Length:  2x

Equation:

Area = (L) (W)

(x) (2x) = 200

2x²  = 200

2x²/2 = 200/2

x² = 100

 \sqrt{ x^{2} } = \sqrt{100}

x = 10

DIMENSIONS:
Width: x = 10 ft.
Length: 2x ⇒ = 2(10 ft) = 20 ft.

ANSWER:  The length is 20 ft, while the width is 10 ft.

CHECK:
(10 ft) (20 ft) = 200 ft²
200 ft² = 200 ft²      (True)
