Question

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

Answer 1

The area of square flake of gold is
`53.29 * 10^(-8) \mathrm{mm}`

Solution:

Given that width of square flake of gold is
`7.3 * 10^(-4)` 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:

`area = s^2`

where "s" is the length of one side

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

Hence , the calculated area of flake is
`53.29 * 10^(-8) \mathrm{mm}`
