Answer 1

Answer:

Area covered by carpet = 416m²

Area uncovered by carpet = 184m²

Step-by-step explanation:

Area covered by carpet = l×b

                                        = (30m-4m)×(20m-4m)

                                        = 26m×16m

                                        = 416m²

Area of the hall = l×b

                          = 30m×20m

                          = 600m²

Area uncovered by carpet = 600m² - 416m²

                                            = 184m²
