a medical assistant needs to apply a triangular wound dressing to a patients injury. the sides of the triangular dressing measure 5 cm, 6 cm, and 10 cm. to ensure the dressing is the right size, the medical assistant needs to calculate the perimeter. what is the perimeter of the dressing?

Explanation:

Sum the side lengths of the first triangle

$$ P_1 = 14\text{ cm} + 13\text{ cm} + 12\text{ cm} = 39\text{ cm} $$

Sum the side lengths of the second triangle

$$ P_2 = 5\text{ cm} + 6\text{ cm} + 10\text{ cm} = 21\text{ cm} $$

Answer:

Question 1

• (A) 40 cm
• (B) 30 cm
• (C) 39 cm (Correct answer)
