area of new playground = 63 *43 ( since extended by 3m ) = 2709m2

extended area = 2709 - 2400 = 309m2

=60*40

=2400m2

lenght of the extended path along the lenght=60+(3+3)

=66m

breadth of the extended path along the breadth=40+(3+3)

=46m

area of both extended area and play ground =46*66

=3036m2

area of the extended path=area of both - area of play ground

=3036-2400

=636m2
