The sum of the distances of R to Q and P to Q is 9 units.
Solution:
Given points are P(–3, 6), Q(3, 6) and R(3, 3).
Distance between two points formula:
Distance from R to Q:
Here
Substitute these in the given formula, we get
Distance =
= 3 units
Distance from R to Q is 3 units.
Distance from P to Q:
Here
Substitute these in the given formula, we get
Distance =
= 6 units
Distance from P to Q is 6 units.
Sum of the distances = 3 + 6 = 9 units
Hence the sum of the distances of R to Q and P to Q is 9 units.
