If the length and width of a rectangle are each multiplied by 3, how would the new area of the rectangle compare with the original area of the same rectangle?

would it be 9 times greater?

    yes~ :)

    original area:
    A = L*W
    new area:
    A' = (3L)*(3W)
    A' = 9*(L*W) or
    A' = 9*A

    thus there is no correct answer in the choices, since the new area is 9 times greater than the original.

    hope this helps~ :)
