Question
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?
I'm not sure about this one-these are my choices:my choice is A but I'm not sure
a. the new volume will be 1/2 as big as the original
b. the new volume will be 2 times bigger than the original
c. the new volume will be 1/8 as big as original
d. the new volume will be 8 times bigger than original

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~ :)

oh, i see.. the choices are wrong. i guess you typed it wrong because "volume" is in the choices.. it must be "area" since it is the required. (and rectangles don't have volume)
