Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board.

Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area.

Adam says he knows another way.

Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board.
