Rounding each value to the nearest single-significant-digit approximation, that would be
90x60x2
I'd choose that instead of 100*60 because in that case both values are rounded up, making the estimate too high.
Choices:
100 x 60 x 1.5
100 x 60 x 2
90 x 60 x 2
90 x 60 x 1.5
90x60x2
I'd choose that instead of 100*60 because in that case both values are rounded up, making the estimate too high.
93 * 58 * 2.47 = 13,323.18
now
6000*1.5 = 9,000
6000*2 = 12,000
the last two are even lower
The area of a rectangle can be calculated by multiplying its length by its width. In this case, the length is 93 feet and the width is 58 feet. So the area of the parking lot is 93 feet * 58 feet = 5394 square feet.
Now, we can multiply the area of the parking lot by the cost per square foot of $2.47 to find the estimated cost of resurfacing the parking lot.
Next, we need to check which of the choices provided gives us an estimate closest to the actual cost of resurfacing the parking lot, which is incorrectly estimated at $12,000.
Let's calculate the estimated costs for each of the choices:
1. 100 x 60 x 1.5 = 9000 square feet (area of the parking lot) * $2.47 per square foot = $22,230
2. 100 x 60 x 2 = 12,000 square feet (area of the parking lot) * $2.47 per square foot = $29,640
3. 90 x 60 x 2 = 10,800 square feet (area of the parking lot) * $2.47 per square foot = $26,676
4. 90 x 60 x 1.5 = 8100 square feet (area of the parking lot) * $2.47 per square foot = $20,007
The estimate that is closest to the actual cost of resurfacing the parking lot, which is $12,000, is the one with the cost closest to $12,000. In this case, the estimate of $22,230 (choice 1) is the closest.
Therefore, the answer is 100 x 60 x 1.5.
