Question

ramona is installing a kitchen counter that is 9 feet by 3 feet. the counter has a hole in it for a sink that is 2 feet by 3 feet. what is the area of the kitchen counter? complete the equation to calculate the area. (□ × 3) - (2 × □) = □ ft²

Explanation:

Step1: Calculate area of counter

The counter is a rectangle with length 9 ft and width 3 ft. The area of a rectangle is length × width, so the area of the counter is \( 9 \times 3 \).

Step2: Calculate area of sink hole

The sink hole is a rectangle with length 2 ft and width 3 ft. The area of the sink hole is \( 2 \times 3 \).

Step3: Subtract sink area from counter area

To find the area of the kitchen counter (excluding the sink), we subtract the area of the sink from the area of the counter. So the equation is \( (9 \times 3) - (2 \times 3) \). Now calculate the values: \( 9\times3 = 27 \), \( 2\times3 = 6 \), then \( 27 - 6 = 21 \).

Answer:

\( (9 \times 3) - (2 \times 3) = 21 \) ft²
