Carlos is tiling a kitchen cluster that is 12 feed by 3 feed. The counter has a rectangular hole 3 feet by 2 feet cut in ir for
Taya2010 [7]

Answer:

The area of the counter that Carlos will wall tile is 30 ft^{2}

Step-by-step explanation:

to solve this, we will calculate the area of the counter and the area of the rectangular hole that Carlos would have to leave out for the sink, and then subtract them to get the area that will be tiled.

Total area of the rectangular counter = length X breadth = 12 \times 3 = 36ft^{2}

area of the rectangular cut out for the sink = length X breadth =3 \times  2 = 6 ft^{2}

Surface area that Carlos is meant to tile = 36ft^{2}- 6 ft^{2} = 30ft^{2}

Hence,the area of the counter that Carlos will wall tile is 30 ft^{2}
