Question

The points N(-3,-3)(−3,−3), O(-3,-9)(−3,−9), and P(5,-3)(5,−3) form a triangle. Plot the points then click the "Graph Triangle" button. Then find the perimeter of the triangle. Round your answer to the nearest tenth if necessary.

Answer 1

Answer:

Perimeter = 30.42

Step-by-step explanation:

Using Distance Formula, √((x2-x1)^2 + (y2-y1)^2)

Find the Distance Between NO, OP, and NP

√((-3 - -3)^2 + (3 - 9)^2) - NO = 6

√((-3 - 5)^2 + (9 - -3)^2) - OP = 14.42

√((-3 - 5)^2 + (3 - -3)^2) - NP = 10

Sum All of Them = 10 + 6 + 14.42 = 30.42
