Actually it's 5 because there is no decimal space and if you only include 8 then that means the number is actually 8.

Answer:

The answer to your question is 20 feet

Step-by-step explanation:

Data

A = (-2, 1)

B = (4, 1)

C = (-2, -3)

D = (4, -3)

Process

1.- Calculate the distance from C and D

dCD = $\sqrt{(4 + 2)^{2} + (3 - 3)^{2}}$

dCD = $\sqrt{6^{2}}$

dCD = 6

2.- Calculate the distance from A to C

dAC = $\sqrt{(2 - 2)^{2} + (-3 - 1)^{2}}$

dAC = $\sqrt{4^{2}}$

dAC = 4

3.- Calculate the perimeter

Perimeter = 2(dCD) + 2(dAC)

-Substitution

Perimeter = 2(6) + 2(4)

-Simplification

Perimeter = 12 + 8

-Result

Perimeter = 20 ft
