Parameters are the words and numbers between the parentheses of our rectangle. Each parameter controls one part of what the rectangle looks like.

• The rectangle's fourth parameter is its height parameter. Change the height parameter to top_height.

You can use the grey comment above the rectangle code as a guide for what each parameter controls.

Make sure you don't delete the commas that separate each parameter.
