Question

1. if point p is on line segment qr, and qp = 7 units and pr = 12 units, what is the length of qr?

a) 5 units
b) 19 units
c) 84 units
d) 1.7 units

○ a) 5 units
○ b) 19 units
○ c) 84 units
○ d) 1.7 units

Explanation:

Step1: Identify segment - addition principle

Since point P is on line segment QR, then $QR = QP+PR$.

Step2: Substitute given values

We know that $QP = 7$ units and $PR = 12$ units. So $QR=7 + 12$.

Step3: Calculate the result

$7+12=19$ units.

Answer:

B. 19 units
