1. Computing Actual Lengths From a Scale Drawing Learning Target I can compute actual lengths in a picture using the scale.

2. Find the length and the width of the basketball court based on the drawing. Find the width of the court. Find the scale factor. Scale factor: scale = Actual 1 in = 15 ft 1 in = 15 ft *12 in Scale Factor 1 in 180 in Use a proportion. 1 in = 2 in. 15 ft x Cross Multiply 1x = 15 * 2 x = 30 ft. Width= 30 ft

3. Find the length the court.

4. Find the length.1 cm = 20 meters 8 cm x 20 meters = 160 meters Find the width. 1 cm = 20 meters 4 cm x 20 meters = 80 meters

5. 1 1/8 in. 1 ½ in. Find the width. Use the scale factor in a proportion. Convert the mixed number to a fraction first. 0.25 in. = 9/8 in. 1 in. x

6. 1 1/8 in. 1 ½ in.
