Asked by Selina_jeyaraj | 18 Nov, 2018, 08:19: PM
answered-by-expert Expert Answer
Perimeter of square field = 4×a  = 4×65 = 260 m
 
Perimeter of rectangular field = 2(l+b) = 260 m
 
hence l+b = 130 m ; if we consider length l = 75, then breadth b = 130-75 = 55 m
 
Area of square field = 65×65 = 4225 sq.m
Area of rectangular field = 75×55 = 4125 sq.m 
 
area of square field is more by 100 sq.m
