The area of a square with sides of 2 feet is 4 square feet. the area of a square with sides of 4 feet is 16 square feet. what equation fits this data?
choices

y=4x
or
y=x+2
or
y=x squared
or
y=2x

A square, by definition, is an equilateral quadrilateral. It has already been established that the formula for the area of a square is to take the square of the length of its one side. To prove this,

A = 2^2 = 4
A = 4^2 = 16

Thus, the equation is y = x squared
