Question
If P is a moving point in the xy-plane in such a way that perimeter of triangle PQR is 16 {where Q ≡ (3, √5), R ≡ (7, 3 √2)} then maximum area of triangle PQR is :-
Options
A.6
B.12
C.18
D.9
Solution
A =
× 6 × PM area will be maximum when PM is maximum and for PM to be maximum triangle will be isosceles. Hence PM = 4, A = 12.Create a free account to view solution
