Triangle PQR has vertices at A2, 4), Q15, 6) and R(8,4).

Fran believes that the perimeter of APQR is 18 square units.

Explain why Fran is incorrect.

A. Because PQ= V5 units, QR = 5 units and PR = 6 units.

O

B. Because PQ= 6. 5 units, QR = 6. 5 units and PR = 18 units.

o

C. Because PQ= V13 units, QR = ~ 13 units and PR = 6 units.

O

D. Because PQ = 13 units, QR = 13 units and PR = 36 units.
