838 inchesĀ²

Step-by-step explanation:

Finding the area of the countertop including the hole

ā‡’ Area of countertop including hole: LB

ā‡’ Area of countertop including hole: (24)(48)

ā‡’ Area of countertop including hole: 1152 inchesĀ²

Finding the area of the hole (sink)

ā‡’ Area of hole: Ļ€rĀ²

ā‡’ Area of hole: (Ļ€)(D/2)Ā²

ā‡’ Area of hole: (Ļ€)(20/2)Ā²

ā‡’ Area of hole: (Ļ€)(10)Ā²

ā‡’ Area of hole: (Ļ€) x 100

ā‡’ Area of hole: 3.14 x 100 = 314 inchesĀ²

Finding the area excluding the hole

1152 - 314 = Area of countertop (excluding the hole)

838 inchesĀ² = Area of countertop (excluding the hole)
