Alice’s backyard is a rectangular piece of property that is twice as long as it is wide. The total area of her yard is 1 comma 000 m squared What is the approximate width of her backyard? cap A is equal to l w

Let the width be w, so the length is 2w. Using A = lw, the area is 2w² = 1,000, which gives w = √500 ≈ 22.4 m. Therefore, the approximate width is 22.4 m, choice B.
