Sorry.
The situation above described that Jeff added two - thirds of 128 to the flour. The numerical value of (2/3)(128) is 85.33 grams. The recipe says to add only 32 grams of vanilla powder. Hence, Jeff went over the prescribed amount.
To determine the excess amount, subtract 32 from 85.33 which has a numerical value of 53.33 grams.
The squares area can be calculated by multiplying width and length. Since these values are the same for the square, we can use exponents.
(6)^2 - (3)^2 - (2)^2 = area
The area is 23 square inches.
