Ratio=16:9

Let length be 16x

and breadth be 9x

perimeter=750cm

perimeter of a rectangle = 2(l+b)

750=2(16x+9x)

750=2(25x)

750=50x

x=750/50

x=15cm

so length of rectangle=16x=16X15=240cm

and 9x = 9X15= 135cm

We know area of a rectangle =l X b

=240 X 135

=32400cm sq.

Therefore the answer to this question is (b)32400
