Question

The formula shows that A, the area of a square, depends on s, the length of the sides of a square. A = s². What is the independent variable in the formula?

Answer 1

A variable is called independent when its value is independent of other variables.

For example, the side length doesn't depend on the area value.

A variable is dependent when its value is dependent of other variables.

For example, the area value depends on the side length value.

Therefore, in the formula A = s², the independent variable is s.
