Answer: 21
Step-by-step explanation:
since 19 is the breadth and the perimeter is 80m, so 19*2=38 and 80-38= 42 so 42/2=21. The answer is 21
The mass of radioactive material remaining after 50 years would be 48.79 kilograms
<h3>How to determine the amount</h3>
It is important to note that half - life is the time it takes for the amount of a substance to reduce by half its original size.
Given the radioactive decay formula as
m(t)=120e−0.018t
Where
t= 50 years
m(t) is the remaining amount
Substitute the value of t
![m(t) = 120e^-^0^.^0^1^8^(^5^0^)](https://tex.z-dn.net/?f=m%28t%29%20%3D%20120e%5E-%5E0%5E.%5E0%5E1%5E8%5E%28%5E5%5E0%5E%29)
![m(t) = 120e^-^0^.^9](https://tex.z-dn.net/?f=m%28t%29%20%3D%20120e%5E-%5E0%5E.%5E9)
Find the exponential value
m(t) = 48.788399
m(t) = 48.79 kilograms to 2 decimal places
Thus, the mass of radioactive material remaining after 50 years would be 48.79 kilograms
