## Question

A thin metal square plate has length *l*. When it is heated from 0^{o}C to 100^{o}C, its length increases by 1%. What is the percentage increase in the area of the plate?

### Solution

Since the length increases by 1%, the length at 100^{o}C is

The area of the square plate at 100^{o}C will be
