The  minimum number  of bricks Salah will have to buy is  4050 bricks            How to find the minimum number of bricks Salah will have to buy?   Given that the   width of the garden is w = 17 feet and   length l = 40 feet.   Also, the walkway iis 18 feet wide.    So, the length of walkway plus garden, L = 40 ft + 18 ft = 58 ft. The width of walkway plus garden, W = 17 ft + 18 ft = 35 ft.    The area of the walkway  We now need to find the area of the walkway.   Area of walkway, A' = area of walkway plus garden - area of garden   = LW - lw   = 58 ft × 35 ft - 40 ft × 17 ft   = 2030 ft² - 680 ft²   = 1350 ft²    Now, since each brick is 6 inches wide and 8 inches long, the area of each brick is A' = 6 in × 8 in  = 48 in²     So, the  number  of  bricks  required,  n = area of walkway/area of brick    = 1350 ft²/48 in²   = 1350 × 144 in²/48 in²   = 194400 in²/48 in²    = 4050 bricks       So, the  minimum number  of  bricks  Salah will have to buy is  4050 bricks       Learn more about  minimum number  of  bricks  here:  https://brainly.com/question/14458421  #SPJ1
