Question

The area of this square

Answer 1

It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.

The area of a square is given by the equation $A=s^{2}$ where s is the length of the side.  

$A=24^{2}$

A=576

The area of this square is 576cm2.

Hope this helps!
