Explanation:

Step1: Calculate area of countertop

The area of a rectangle is $A = l\times w$. The counter - top is 9 feet by 3 feet, so its area $A_{1}=9\times3 = 27$ square feet.

Step2: Calculate area of sink hole

The sink hole is 2 feet by 3 feet, so its area $A_{2}=2\times3=6$ square feet.

Step3: Calculate net area of countertop

The net area of the kitchen counter $A = A_{1}-A_{2}$. Substitute the values of $A_{1}$ and $A_{2}$: $A=27 - 6=21$ square feet.

Answer:

21 square feet
