A scientist measured the width of a square flake of gold to be7.3 x 10 -4mm what is the area of the flake

irakobra [83]

The area of square flake of gold is $53.29 \times 10^{-8} \mathrm{mm}$

<h3><u>Solution:</u></h3>

Given that width of square flake of gold is $7.3 \times 10^{-4}$ millimeter

To find : Area of square flake

Since gold flake is in shape of square, we can use area of square formula

<em><u>The formula for area of square is given as:</u></em>

$area = s^2$

where "s" is the length of one side

$\begin{array}{l}{\text { Area of a square flake }=\left(7.3 \times 10^{-4}\right) \times\left(7.3 \times 10^{-4}\right)} \\\\ {\text { Area of a square flake }=53.29 \times 10^{8}}\end{array}$

Hence , the calculated area of flake is $53.29 \times 10^{-8} \mathrm{mm}$
