P = 20.48 m
Explicación paso a paso:
(2, 1) B _________ C (5,-2)
Ι Ι
Ι Ι
(-2, 1) A Ι Ι D(-5,-2)
A = (-2, 1)
B = (2, 1)
C = (5,-2)
D = (-5,-2) __ __ __ __
Calcular segmentos: AB, BC, CD, AD
AB segmento
A = (-2, 1) B = (2, 1)
x₁ y₁ x₂ y₂
AB = √(y₂ – y₁)² + (x₂ – x₁)²
AB = √(1 - 1)² + (2 – (-2))²
AB = √ (0)² + (2 + 2)²
AB = √4
B = (2, 1) C = (5, -2)
x₁ y₁ x₂ y₂
BC = √(-2 - 1)² + (5 – 2)²
BC = √(-3)² + (3)²
BC = √(9) + (9)
BC = √18
C = (5, -2) D = (-5, -2)
x₁ y₁ x₂ y₂
CD segmento
CD = √(-2 - (-2)² + (-5 – 5)²
CD= √(-2 + 2)² + (10)²
CD = √100
AD Segmento
AD = (-2, 1) B D = (-5, -2)
x₁ y₁ x₂ y₂
AD = √(-2 - 1)² + (-5 – (-2))²
AD= √(-3)² + (-3)²
AD = √(9 + 9)
AD = √18
P = AB + BC + CD + AD
P = √4 + √18 + √100 + √18
P = 20.48 m
