Area is length times width. Our length and width are 4 5/8 and 1/2 respectively, so the formula for the area is

. It will be easier to get that mixed fraction into an improper one and then multiply the fractions straight across the top and straight across the bottom.

. Doing that multiplication gives us

, choice B.
