Above are two different models of the same television. If the screen in the model on the left has a 13-cm diagonal, what is the diagonal of the screen in the model on the right?
Assuming both models have the same aspect ratio, we can use the ratio of diagonal lengths to find the diagonal of the screen in the model on the right.
Let the diagonal of the screen in the model on the right be D cm.
Using the ratio of diagonal lengths between the two screens:
D_left / D_right = 13 / D
Rearranging the equation:
D_right = D_left * D / 13
Given that D_left = 13 cm:
D_right = 13 * D / 13
D_right = D
Therefore, the diagonal of the screen in the model on the right is also 13 cm.
