Answer 2

Explanation

Our task is to find the area of the square mirror. One of its sides is equal to 4 ft.

The area of a square is given by
`A=x^2` where x is the side length.

We know the value of x, it's 4, so we put it into the formula:

`A=4^2`

`A=16\;cm^2`

Therefore, the mirror's area is 16 cm².
