First we need the distances of the sides of the polygon, because perimeter = sum of all sides.
Now, we add all sides for the perimeter:
p = d1 + d2 + d3 + d4 + d5
p = 3+5+5+3+4 = 20 units
Now, we add all sides for the perimeter:
p = d1 + d2 + d3 + d4 + d5
p = 3+5+5+3+4 = 20 units
Answer:
D.
Step-by-step explanation:
Consider the set
This set consists of four ordered pairs.
The first numbers in these pairs are These numbers are integer numbers (not natural, because -3 is negative).
The second numbers in these pairs are These numbers are integer numbers too (not natural, because -2 is negative).
Options contain only natural and real sets, so, the first and the second numbers are real numbers and
