Find the perimeter of the right triangle. If necessary, round to the nearest tenth. 12 mi 16 mi 20 mi b. 16 mi C. 48 mi d. 96 mi

C. 48 mi

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

P = a + b + c

Since we have a right triangle, we can find the missing side length and figure out our perimeter.

Step 1: Find missing length

12² + 16² = c²

144 + 256 = c²

400 = c²

c = 20

Step 2: Find perimeter

P = 12 + 16 + 20

P = 28 + 20

P = 48
