side of the square field =70m
thus area=(70×70)m
or area =4900m^2
diameter of circle =70m
radius=35
thus area =22/7 ×35×35
or area=3850m^2
so area of the square excluding the lawn =(4900- 3850)m^2
=1050
thus area=(70×70)m
or area =4900m^2
diameter of circle =70m
radius=35
thus area =22/7 ×35×35
or area=3850m^2
