Step-by-step explanation:
The answer for this will be a
Answer:
72.14 units
Step-by-step explanation:
Let A(8,13), B(5,-18),C(-6,-6) and D(-2,-5)
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
The answer to this question is 58. This works because 5h = 5 * h and since h = 12 then that equals 60 and then you minus 2 from 60 and your answer is 58.
