Four circle ponds are constructed as shown in the above figure with radius 5m each. In the shaded area at the shaded area at the centre (shown by S), a show case has to be built which costs Rs.200 per sq.m. and in the dotted area( shown by T) ,tiles are to be embedded which costs 200per sq.m. Also, a foot path of 2m width width has to be constructed as shown which costs Rs.100/sq.m. The total cost (In Rs.) involved for the whole contruction is :
