We need to find the area of the concrete borders. The swimming pool is of dimensions 25m by 10m. The concrete border at the sides which are 25 m each is 2.5 m wide and is 5 m wide at the ends of 10 m each.
The area of the border is:
25*2.5*2 + 10*2*5
=> 25*5 + 10*10
=> 125 + 100
=> 225 m^2
The required area of the concrete border is 225 m^2.
