The given points are:

A -4 3

B 0 2

C 2 4

D 0 -3

We use the distance formula to calculate for the length of each segment.

D^2 = (x2 – x1)^2 + (y2 – y1)^2

For segment AB:

D^2 = (0 + 4)^2 + (2 – 3)^2 = 17

D = sqrt 17

For segment BC:

D^2 = (2 - 0)^2 + (4 - 2)^2 = 8

D = sqrt 8

For segment CD:

D^2 = (0 - 2)^2 + (-3 – 4)^2 = 53

D = sqrt 53

For segment DA:

D^2 = (-4 - 0)^2 + (3 + 3)^2 = 52

D = sqrt 52

Getting the sum of all the segments will give the perimeter.

Perimeter = sqrt 17 + sqrt 8 + sqrt 53 + sqrt 52

Perimeter = 21.44

Using the GCF you found in Part B, rewrite 72 + 81 as two factors. One factor is the GCF and the other is the sum of two numbers
