Let the length of the side of the square be X. Then
length of the rectangular field is equal to (x - 5 )m
breadth of rectangle is equal to (X + 5) m
area of rectangular field is equal to (X + 5 )× (x - 5 )
therefore (X+5)×(X-5)m^2 = 1200m^2
=X^2 -5X + 5X -25 =1200
X^2 = 1225
X = 35m
now length of rectangle is equal to (35-5)m =30m
and breadth of rectangle is equal to (35+5)m = 40m
Hope it help you.
