Question

Which equation could represent "the area of a square as a function of a side"?

A(s) = 2s
A(s) = 4s
A(s) = s2

Answer 1

A(s) = s^2

it says use at least 20 characters lolol

Answer 2

Let

s-------> the side length of a square

we know that

The area of a square is equal to

`A=s^(2)`

convert to function notation

`A(s)=s^(2)`

therefore

the answer is

`A(s)=s^(2)`
