Question

What is the perimeter of triangle PQR whit vertices p(-2,-3) Q(7,-3) and R(-2,-3) in the coordinate plane

Answer 1

you have P( - 2 , - 3) and R( - 2 , -3) the same point. Have you copied the coordinates correctly ?

Answer 2

PQR with vertices P(–2, 9), Q(7, –3), and R(–2, –3)

first distance P(–2, 9), Q(7, –3)

The distance (d) between two points is given by the following formula:

Answer= 15
