Answer: The fossil is 11459 years old.
Explanation:
Half-life of carbon-14 = 5700 years
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the age of the sample:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =

The fossil is 11459 years old.
The Gibraltar rock is a limestone, therefore it is a sedimentary rock. Sedimentary rocks are made by the dethronement and squeezing of small fragments.dimentary rock. It has sediments.
