1 of 6

Johnny's square bedroom measures 12 feet by 12 feet. If the area of his square closet is
one-fourth the area of his bedroom, which of the following could be the dimensions of his
closet?
3 ft by 3 ft
4 ft by 4 ft
6 ft by 6 ft
24 ft by 24 ft

Respuesta :

Answer:  6 ft by 6 ft  (choice C)

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

Check:

  • A = bedroom area = 12*12 = 144 sq ft
  • B = closet area = 6*6 = 36 sq ft
  • C = B/A = 36/144 = 1/4 to show that the closet is one-fourth in area compared to the bedroom.

The answer is confirmed.
