Mathematics: You are creating a model of a bookcase for a dollhouse. The actual bookcase is 48 inches tall and 32 inches wide. If you plan to make the model 3 inches tall, how wide do you have to make the model if you want the rectangular shapes of the bookcases to be similar figures?

If the model is 3 inches tall, the model bookcase should be 2 inches wide.

Step-by-step explanation:

When using similar figures, set up a proportion of the model measurements to the actual measurements:

$\frac{3}{48}=\frac{x}{32}$

Then cross multiply and solve for x:

$48x=96\\x=\frac{96}{48}\\x=2$

If this helped, a brainliest would be greatly appreciated!
