Math 7B Area and Perimeter
These are 100% CORRECT!
1. 42 square units
2. 6 feet
3. 24 square miles
4. 33 centimeters
5. 6 feet
6. 1.5 units

9. 565.2
10. 1190.06
11. 2375.48
12. 30156.56
13. 3
14. R = 279, C = 1752.12, A = 244420.74
15. You MUST word this final question yourself. The formula is A = 1/2 x b x h
(New base and old base) 10/25 = 2/5
(Now multiply original height by new scale factor) 15 x 2/5 = 6 inches
(Now find are of triangle with A = 1/2 x b x h) A = 1/2 x 10 x 6 = 1/2 x 60 = 30
