Question

the new length of a rectangle is 4 times the original length.  the new width is 2 times the original width. how many times greater is the area of the new rectangle than that of the original rectangle

anonymous · Answer

Let L be the length and W be the width of the original rectangle. Then the area A = LW, so you can let 4L be the length of the new rectangle and 2W be the width of the new rectangle, so the area would be (4L)*(2W) and how does that answer compare to the area of LW?
