Here is your answer in the picture.

Answer 2

Answer:

Area of enlarged flower bed = 9.61 meter²

Increased Area = 1.77 meter²

Step-by-step explanation:

Side of square flower bed = 2 meter 80 cm

1 meter = 100 cm

⇒ 2 meter 80 cm = 200 + 80 = 280 cm

Area of square = side²

⇒ Area of flower bed = 280²

                                    = 78400 cm²

                                    = 7.84 m²

Length of flower bed after extension = 280 cm + 30 cm

                                                              = 310 cm

Area of enlarged flower bed = 310²

                                                = 96100 cm²

                                               = 9.61 meter²

Increased Area = 9.61 - 7.84

                          = 1.77 meter²
