Explicación paso a paso:
dAB = √(2-(-2))² + (-1-2)²
dAB = √(2+2)² + (-3)²
dAB = √(4)² + (-3)²
dAB = √16 + 9
dAB = √25
dAB = 5
dAC = √(2.6-(-2))² + (3.96-2)²
dAC = √(2.6+2)² + (1.96)²
dAC = √(4.6)² + (1.96)²
dAC = √21.16 + 3.84
dAC = √25.00
dAC = 5
dBC = √(2.6-2)² + (3.96-(-1))²
dBC = √(0.6)² + (3.96+1)²
dBC = √(0.6)² + (4.96)²
dBC = √0.36 + 24.6016
dBC = √24.9616
dBC = 4.99 ≈ 5
Perímetro (P) = a + b + c
Perímetro (P) = dAB + dBC + dAC
Perímetro = 5 + 5 + 5
Semiperímetro (s) = P /2 = 15/2 = 7.5
Área conociendo el semiperímetro (aplicando la Fórmula de Herón)
A = √s(s-a)(s-b)(s-c)
A = √7.5(7.5-5)(7.5-5)(7.5-5)
A = √7.5(2.5)(2.5)(2.5)
A = √117.1875
A = 10.82 u²
