Step-by-step explanation:
We solve for this using Newton's Law of cooling.
The formula for Newton's Law of cooling =
T −Ts = (To−Ts)e^-kt
T = Temperature after cooling
To = Initial temperature
Ts = Room temperature
k = constant
t = time = 2 mins
(200 - 70) = (205 - 70)e^-2k
130 = 135e^-2t
e^-2k= 130/135
k = In(130/135)/-2
k = 0.018870164
Approximately to 4 decimal places = 0.0189
Therefore, the value of k = 0.0189

There are three lines along the length that indicate that the lines are the same length.
Out of all the choices, 15 is the only number that is divisible by 3. So the total length of the shape would be 15
