This is a relatively straightforward question, especially if you draw a schematic of the problem (see attached file).

Given information:- 9 x 9 inch square pan

- 1.5 x 1 inch bar of cake

Objective:Determining the number of bars that would fit the square pan

Procedure:Length-wise, for 9 inches, we would have 6 bars of cake. This comes from dividing the length of the bar by that of the pan: \(\frac{9}{1.5} = 6\)

Width-wise, for 9 inches, we would have 9 bars of cake. This is evident as the width of the bar is 1 inch and that of the pan is 9 inches.

Therefore, the total number of bars that would fit the square pan is: \(6 * 9 = 54\)

This corresponds to answer

A.
