Answer:
The answer to your question is 20 feet
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)}](https://img.qammunity.org/2021/formulas/mathematics/college/kcbqe799x0t4i0b0wwcjhwgv52ifa7u1f3.png)
dCD =
![\sqrt{6^(2)}](https://img.qammunity.org/2021/formulas/mathematics/college/w82cldzhylkdccvd4y8fxap6bx6mxnw57o.png)
dCD = 6
2.- Calculate the distance from A to C
dAC =
![\sqrt{(2 - 2)^(2) + (-3 - 1)^(2)}](https://img.qammunity.org/2021/formulas/mathematics/college/nmqavaql8itsv15v0ffw14d9zti3ifinrw.png)
dAC =
![\sqrt{4^(2)}](https://img.qammunity.org/2021/formulas/mathematics/college/wre0u6g4z0iyvnjvk0nd6111yhcssx7omm.png)
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
