Solution:
Let the length of the chocolate bar is L and the width be W.
The area of the chocolate bar is expressed as
[tex]\begin{gathered} \text{Area = length}\times width \\ =L\times W \end{gathered}[/tex]
Given that the area of the chocolate bar is 47.94 square feet, we have
[tex]\begin{gathered} A=L\times W \\ \Rightarrow47.94=LW\text{ ---- equation 1} \end{gathered}[/tex]
