http://www.usatestprep.com/modules/gallery/files/23/2351/2351.gif Sally is calculating the perimeters of a number of rectangles, such as the one shown here. She uses the formula P = 2l + 2w. Her younger brother Joe comes by and suggests simplifying the formula to P = 4w. Sally corrects Joe's algebra, but he tries his formula on a rectangle and gets the correct answer! (She checks his work.) What can Sally conclude from this? A) Joe's rectangle is oblong. B) Joe's rectangle is a square. C) Joe's rectangle has no length. D) Joe's rectangle wider than it is

B. Joe's rectangle is a square. The formula for the perimeter of a square is x+x+x+x or 4x **Some rectangles are squares because it holds the properties of a square, as it this case, though it won't happen all the time**
