Question

In the square, A represents the area of the square. Find the value of A such that A is equal to two times the side of the square.

Answer 1

Recall, the area of a square is the side length squared, call side length X, then Area A

A = x^2

Answer 2

It also says the area is 2 times the side length...
A = 2*x

together this gives

A = x^2 = 2x

Answer 3

so you can solve that for a value of x...

x^2 = 2x

x^2 - 2x = 0

x*(x - 2) = 0

x = 0
or
x - 2 = 0
