In the given figure, PQRS is a rectangle with its centre at origin and length
PQ = 2a units and breadth QR = 2b units. Find coordinates of all of its vertices.
A P(a, – b), Q(a, b), R(–a, b), S(–a, –b)
B P(a, – b), Q(a, b), R(a, – b), S(–a, –b)
C P(–a, b), Q(a, b), R(a, – b), S(–a, – b)
D P(–a, b), Q(a, b), R(a, – b), S(–a, b)
