Step-by-step explanation:

Find Area of the grass

Area of the grass = area of the garden - area of the patio

                             =  (lw) - (¹/₂ bh)

                             = (12 m × 7 m) - (¹/₂ (6m × 3m))

                            = 84 m² - 9 m²

                            = 75 m

Determine how many boxes are needed

Since one box contains 32 m²

the number of boxes needed = 75 m² ÷ 32 m²

                                                 = 2.34375    

                               (so three boxes in total)
