Side of a square plot= 60m
Perimeter of the square plot
= 4 X S
= 4 X 60
=240m
P of squar plot = P of rectangular plot
P of rectangular plot = 2(l+b)
240 = 2(l+15)
240 = 2l + 30
2l = 240-30
2l = 210
l = 105m
A of square plot = 60 X 60
=3600 square metres
A of rectangular plot = 105 X 15
= 1575 square metres
Therefore, area of the square plot is greater by (3600-1575) 2025 square metres.
