Apply the distance formula as;
Finding the lengths of the segments
For AB
For BC
For CD
For DA
Finding the perimeter will be;
31.14+16.28+4.12+20.6=72.14 units
Compute the simplified numerical value of the expression: (4042 + 4040 + 4038 + … + 6 + 4 + 2) − (4041 + 4039 + 4037 + … + 5 + 3

Answer: FIRST OPTION.
Step-by-step explanation:
For this exercise it is important to remember a property called "Quotient of Powers property".
By definition the Quotient of Powers property states the following:
You can observe the division of and
. Since both have the same base "a" , you must rewrite the base and subtract the exponents "m" and "n".
In this case, you have the following expression given in the exercise:
Then, you need to apply the Quotient of Powers property rewriting the base 4 and subtracting the exponents 12 and 5.
Therefore, you get the following result:
You can notice that it matches with the first option.
