Reason:
The closet area is 1/4 of the bedroom area.
This means the linear dimensions of the closet are 1/2 of their corresponding counterparts.
Notice how [tex]\sqrt{\frac{1}{4}} = \frac{\sqrt{1}}{\sqrt{4}} = \frac{1}{2}[/tex]
This is because (1/2)*(1/2) = 1/4.
Take half of 12 to get 6. Therefore, the closet is 6 ft by 6 ft

The answer is confirmed.
