First, convert everything to feet.
24 inches become 2 feet, and 30 inches become 2.5 feet.
Then, calculate the square feet of counter top. To do that, multiply length by height.
2 x 6 = 12
2.5 x 4 = 10
Then add them together
10 + 12 = 22
And then calculate per square feet, so multiply 22 by the cost, 42.
22 x 42 = 924
The cost would be $924
There are 12 inches in a foot, so ...
... 24 inches is 2 feet,
... 30 inches is 2.5 feet.
The total area of the existing countertop is
... (2 ft)×(6 ft) + (2.5 ft)×(4 ft)
... = 12 ft² + 10 ft²
... = 22 ft²
Then the cost of new tops will be
[tex](22\,ft^2)\times \dfrac{\$42.00}{1\,ft^2}=\$924.00[/tex]
