Answer: 410 centimeters


Explanation:

1. You know that she put 18 hangers on the wall at 20 centimeters intervals, therefore, the number of spaces is:


spaces=n-1

Where n is the number of hangers put on the wall.

2. Then, you have that the number of spaces is:


spaces=18-1=17

3. So, the width of Leslie's room can be calculated as following:


width=(2*35cm)+(17*20cm)\\width=410cm
