Answer 1

I am no sure but I think answer will be 10*40= 400 if it is wrong then sorry

Answer 2

cost of 1 m² is 11

cost of x m² is 1100

area = 1100÷ 11

         =100 m²

side= √100

     =10 m

perimeter= 4 x s

                  =4 x 10

                  = 40 m

cost of fencing 1m = 10 rupees

cost o fencing 40 m = 10 x 40

                                  = 400 rupees
