Above are two different models of the same television. If the screen in the model on the left has a 11-cm diagonal, what is the diagonal of the screen in the model on the right?
A.
22 cm
B.
66 cm
C.
33 cm
D.
44 cm
C. 33 cm
Since both models have the same shape and proportions, the diagonal of the screen in the model on the right is twice the diagonal in the model on the left. Therefore, 11 cm x 2 = 22 cm.
