<h2>Answer</h2>
It will take Carl 1.76 minutes to run 1.5 laps
<h2>Explanation</h2>We know from our problem that Chris runs a lap in 1.17 minutes, so he will run half a lap in half the time: minutes.
We have the time it takes Chris to run 1 lap and the time it takes him to run half (0.5) laps, so, to find how long it takes him to run 1.5 laps, we just need to add the two times:
Total time = 1.17 minutes + 0.585 minutes
Total time= 1.755
Since we need to round to two places, we check if the number after the 2nd place is 5 or bigger; if it is, we add 1 to the number on the 2nd place. The number after the 2nd place is 5, so we add 1 to the 5 in the 2nd place to get:
Total time = 1.76 minutes
Carl will run 1.5 laps in 1.76 minutes

Answer:
A = 374.123 ft^2
Step-by-step explanation:
First, lets calculate the perimeter:
Perimeter (p) = side length (s) * number of sides (n)
Next, lets find the apothem, which is the shortest length from any side to the middle. It's like the radius in a circle, but more complicated.
Apothem (a) = side length (s) / ( 2 * tan(180/number of sides (n)) )
Now, finally, to find the area of a regular polygon, we use the following equation:
Area (A) = ( apothem (a) * perimeter (p) ) / 2
Turning into a decimal:
