The points P(-3, -2), Q(10, -2), and R(3, -8) are the vertices of a triangle. What is the approximate perimeter of the triangle?

• 9 units

• 22 units

• 35 units

• 13 units

Answer explanation

This is a picture of the three points plotted. See how they create a right triangle. Counting the places between P and R is 6, between P and Q is 7. Use these to find the length of RQ, which is 9.2.

Add up all three values to find the perimeter!
