Lesson 4 – Scale Drawings

Use the scale drawing to find the actual length and width of each room. Then find the actual area of each room.

[pic]

1. master bedroom 2. bedroom 2

15 ft by 12 ft; 180 ft2 12 ft by 12 ft; 144 ft2

3. kitchen and dining area 4. half bath

18 ft by 12 ft; 216 ft2 6 ft by 9 ft; 54 ft2

On a map, the scale is 1 inches = 50 miles. For each map distance, find the actual distance.

5. 5 inches 250 mi 6. 12 inches 600 mi 7. 2 inches 118 mi

8. inch 40 mi 9. 2 inches 141 mi 10. 3.25 inches 162.5 mi
