PQ=√((22-7)²+(9-3)²)=√(225+36)=√261
QR=√((7-(-2))²+(3-(-3))²)=√(81+36)=√117
RP=√((22-(-2))²+(9-(-3))²)=√(576+144)=√720
Perimeter of PQR=√261+√117+√720=53.8
The coords of A have not been provided so we can’t find the perimeter of PAR!
Even if we had the coords of A, PR would still have length √720. The sum of the other two sides must be greater than PR so the perimeter would be greater than 2√720=53.67 approx. None of the answers is close to this, so the question has been misstated.
