Here is a rough sketch of Noah’s bedroom (not a scale drawing). Noah wants to create a floor plan that is a scale drawing. The actual length of Wall C is 4 m. To represent Wall C, Noah draws a segment 16 cm long. Use the app below to help you determine what scale he is using. Explain or show your reasoning.

Here is a rough sketch of Noah’s bedroom (not a scale drawing).
Noah wants to create a floor plan that is a scale drawing.
The actual lengths of Wall A, Wall B, and Wall D are 2.5 m, 2.75 m, and 3.75 m. Determine how long these walls will be on Noah’s scale floor plan.
and the Segment tool 
to draw the walls of Noah's scale floor plan in the applet.If Noah wanted to draw another floor plan on which Wall C was 20 cm, would 1 cm to 5 m be the right scale to use? Explain your reasoning.
A rectangle around Utah is about 270 miles wide and about 350 miles tall. The upper right corner that is missing is about 110 miles wide and about 70 miles tall. Make a scale drawing of Utah where 1 centimeter represents 50 miles.
