Question

The area, A, of a square is a function of the length, x, of a side of the square. Which of the following expresses the function, A(x), and the value at x = 2.5?a. A(x)=2x; 5cm^2b.A(x)=4x; 10cm^2c.A(x)=x^2; 6.25cm^2d.A(x)=4x^2; 25cm^2

Answer 1

We will have that the solution is the following:

`A(x)=x^2;A(2.5)=6.25`

So, the solution would be option C.
