The area of square flake of gold is [tex]53.29 \times 10^{-8} \mathrm{mm}[/tex]
Given that width of square flake of gold is [tex]7.3 \times 10^{-4}[/tex] millimeter
To find : Area of square flake
Since gold flake is in shape of square, we can use area of square formula
The formula for area of square is given as:
[tex]area = s^2[/tex]
where "s" is the length of one side
[tex]\begin{array}{l}{\text { Area of a square flake }=\left(7.3 \times 10^{-4}\right) \times\left(7.3 \times 10^{-4}\right)} \\\\ {\text { Area of a square flake }=53.29 \times 10^{8}}\end{array}[/tex]
Hence , the calculated area of flake is [tex]53.29 \times 10^{-8} \mathrm{mm}[/tex]
