Write a function rule for the area A(n) of a square when you know length n of a side?

An area of a square is its length squared. If the length of the square is n, the area of the square would be n squared.

The function rule for the area A(n) of a square when you know the length n of a side can be expressed as:

A(n) = n^2

In this equation, n represents the length of a side, and n^2 represents the square of that length, which gives us the area of the square.

To find the area A(n) of a square with side length n, you need to square the length of one side.

The function rule for finding the area of a square would be:

A(n) = n^2

In this rule, n represents the length of one of the sides of the square. By squaring the side length, you calculate the area of the square.
