Final answer:

The width of the door on the diagram with a scale of 1:20 would be 1600 cm.

Step-by-step explanation:

The width of the door on the diagram with a scale of 1:20 can be calculated by setting up a proportion. Let x be the width on the diagram. The proportion is: 80 cm / 1 = x cm / 20. Cross multiplying, we get 80 * 20 = x cm * 1, which simplifies to 1600 = x cm. Therefore, the width of the door on the diagram would be 1600 cm.
