Answer:
Explanation:
The easiest way personally for me is to graph it out, but you can also calculate it out.
A = (1,1)
B = (4,4)
C = (7,1)
D = (4,-2)
Attached is the distance formula. Use it to your advantage. Find the slope for all the points:
Point A to B:
=
Point B to C:
=
Point C to D:
=
Point D to A:
=
When you add all of it up, it will equal to
and which simplifies to
.
