The coefficient of linear expansion for a material is `2 xx 10^(-5)//^(@)C` . What will be the percentage change of area if temperature is increased by `100^(@)C` ?

Explanation

To find the percentage change in area when the temperature is increased by \(100^\circ C\), we can follow these steps:

### Step 1: Understand the relationship between linear expansion and area expansion
The coefficient of linear expansion (\(\alpha\)) is given as \(2 \times 10^{-5} / ^\circ C\). The area expansion coefficient (\(\beta\)) is related to the linear expansion coefficient by the formula:
\[ \beta = 2\alpha \]
