Explain how to create a scale drawing of a rectangular room with given dimensions.

• Use a protractor to measure the angles of the room

• Guess the dimensions and draw them freehand

• Measure the length and width of the room and use a chosen scale factor to accurately represent the dimensions on a piece of graph paper.

• Use a random scale factor without measuring the room
