EXPLANATION
The area is given as 24 square feet.
This implies that,

The perimeter of the rectangular field is given as 22 feet.
This implies that,

Or

We make w the subject in this last equation and put it inside the first equation.

When we substitute into the first equation we get;


This implies that,



When l=3, w=24
Therefore the dimension is 3 ft by 8 ft

Answer:
Probability of having the double sided coin is 1 %
Probability of getting heads on the next flip is 50%
Step-by-step explanation:
Based on the information given to us in the question we have a total of 100 coins in the bag and only 1 is double heads. Therefore the probability of you picking the double sided coin is
or 1 % . This probability is not affected by the fact that the coin you chose got heads 7 times in 7 flips.
Since a coin has 2 sides and you do not know whether the coin you have is the double sided coin then you have to assume that it is a normal 2 sided coin. Therefore a normal 2 sided coin has a probability of
or 50% with every flip of getting heads.
