Question: 602
13. 
If AB = 10 and AC = 15, what is the perimeter of the figure above?
- A. 25
- B. 35
- C. 40
- D. 50
Correct Answer: D
Explanation:
The length of AB is the same as all the different heights added together on the right-hand side of the figure. Therefore, the perimeter will contain two lengths of 10. Similarly, the length of AC is the same as all the different lengths added together that are across the figure (in this case, above) AC, so there will be two lengths of 15. To find the perimeter, add all the sides: P = 10 + 10 + 15 + 15 = 50. The correct answer is (D).
