Question

You want to replace the countertops in a kitchen. One counter measures 24 inches by 6 feet. The other is 30 inches by 4 feet. If the new countertop costs $42.00 per square foot, what will be the cost of the new top?

Answer 1

First, multiply to find the total square footage of the counter.

2 ft x 6 ft=12 square feet
2.5 ft x 4 ft=10 square feet
Total square feet of the counter is 22 square feet.

To find the total cost, just multiply the area by the cost per square foot.
$42 x 22=$924

Answer 2

The cost of the new top $924.

Explanation:

You want to replace the counter-tops in a kitchen.

The dimensions of the first counter is 24 inches by 6 feet.

i.e
`24 \text{ inch} * 6 \text{ feet}`

or
`2\text{ feet} * 6 \text{ feet}`

As 1 feet =12 inches

Hence the area of the counter is
`2* 6=12\text{ feet}^2`

The dimensions of the second counter is 30 inches by 4 feet.

i.e
`30 \text{ inch} * 4 \text{ feet}`

or
`2.5\text{ feet} * 4 \text{ feet}`

Hence the area of the counter is
`2.5* 4=10\text{ feet}^2`

Hence, the total area will be
`12+10=22 \text{ feet}^2`

The unit cost of the counter-top is
`\$42.00\text{ feet}^2`

So the net cost will be,

`=42* 22=\$924`
