**To Draw a Plan to Scale.**

Here is a rough sketch of Noah’s bedroom (not a scale drawing), but he 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.

**(1)**. Determine how long these walls will be on Noah’s scale floor plan.

**(2). **Use the Point tool and the Segment tool to draw the walls of Noah’s scale floor plan in the applet.

**To Draw a Plan to Scale.**

**(1). 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.**

**(2). 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 75 miles.**

How do the two drawings compare? How does the choice of scale influence the drawing?
