Question

What is the perimeter of the triangle? Round to the nearest tenth.

12.8 Units

30.5 Units

23.5 Units

19.8 Units

Answer 1

19.8 Units

Explanation:

AB = √(3+2)² + (3-0)² = √34 = 5.8

AC = √(-2-(-4))² + (3+3)² = √40 = 6.3

BC = √(3-(-4))² + (0-(-3))² = √58 = 7.6

perimeter = 5.8 + 6.3 + 7.6 = 19.7
