The diagram of this question is attached with the answer.  Please go through it for better understanding.

Area of Verandah = area of ABCD - area of WXYZ

                              = (L X B) - (l X b)

                              = (11 X 8) - (8 X 5)

                              = 88 - 40  = 48 m2

Cost of tiling 1 m2 = Rs. 40

Cost of tiling 48 m2 = Cost of tiling 1m2 X 48

= Rs. 48 X 40

                                 = Rs. 1920
