Answer:
Let length of rectangular pond = x ft. and breadth of rectangular pond = y ft. Area of rectangular pond \[=xy\] According to the question, \[(x-2)(y+1)=(xy-3)\] \[xy+x-2y-2=xy-3\] \[x-2y=-1\] ?(i) \[(x+1).y=(xy+4)\] \[xy+y=xy+4\] \[y=4\] ...(ii) Putting the value of y in eq. (i), we get \[x-2(4)=-1\] \[x-8=-1\] \[\Rightarrow x=-1+8=7\] Length of rectangular pond = 7 ft. Breadth of rectangular pond = 4 ft. Values: 1. Water is essential for the survival of all living things including street animals. 2. Water is the base of life and no one can live without it.
