The area surface is “20,736”
Answer:
A) C(d,m) = 40 + 55d + 0.13m
B) $448
Step-by-step explanation:
Let 'd' be the number of days and 'm' the number of miles driven.
A) The cost function that describes a fixed amount of $40, added to a variable amount of $55 per day (55d) and a variable amount of 13 cents per mile (0.13m) is:

B) If d = 5 and m =600, the total cost is:

The cost is $448.
The answer is 40 square root of 6.
<span>For the answer to the question above, this is the formula for finding the rectangular base.
P = 2L + 2W</span>Consider the Width being twice as long as the length. If we write it down, it will look like this<span>W= 2 L</span>We'll plug that into the perimeter equation,<span>P = 2L + 2W→ P = 2L + 2(2L)</span>Now, just simplify the equation and problem is solved.
I hope I helped you with my answer.
