Find the area.

Step-by-step explanation:

You know that both figures are similar. So, in order to find the missing area, you need to follow these steps:

1. You must find the scale factor of the the perimeter of the smaller figure to the  perimeter of larger figure. This is the ratio between the perimeters. Since it is a lenght, you know that:

2. Now, you must find the scale factor  of the area of the smaller figure to the area of the larger figure. This is:

3. Set up the following proportion:

4. Finally, you must solve for "A", which is the area of the larger figure:

i believe the correct answer is b.
