Answer:
The answer to your question is: 12.66 units
Step-by-step explanation:
Data
A(-5,4)
B(0,3)
F(-2,1)
Formula
d = √((x2 - x1)² + (y2 . y1)²)
Process
dAB = √((x2 - x1)² + (y2 . y1)²)
dAB = √((0 +5)² + (3 - 4)²)
dAB = √((25) + (-))
d = √26
dAF = √((-2 + 5)² + (1 -4)²)
dAF = √((3)² + (-3)²)
dAF = √18
dBF = √((-2 - 0)² + (1 - 4)²)
dBF = √((-2)² + (-3)²)
dBF = √((4 + 9)
dBF = √11
Perimeter = √26 + √18 + √11
= 5.10 + 4.24 + 3.32
= 12.66 units
