Answer:

Hello , here is the answer for your question :

Area of the border along its length = 4 m x 25 cm

                                                          = 400 cm x 25 cm

                                                          = 10000 cm²

Area of the border along its width  = 3 m x 25 cm

                                                          = 300 cm x 25 cm

                                                          = 7500 cm²

Total area surrounding the border  = 2( (1) + (2) )

                                                           = 2 (10000 cm² + 7500 cm² )

                                                           = 2( 100 m ² + 75 m ² )

                                                           = 2 ( 175 m² )

                                                           = 350 m²

Total cost for printing the border     = 350 m² x 50

                                                           = 17500 m²


btejaswini2003: that should be 17500 only . sorry !
