Question
what is the perimeter of square tuvw?
write your answer as an integer or as a decimal rounded to the nearest tenth.
perimeter = \boxed{} units
Step1: Identificar coordenadas de un lado
Tomamos los puntos $U(3,1)$ y $T(8,5)$.
Step2: Calcular longitud del lado
Usar fórmula de distancia:
$$d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$$
$$d = \sqrt{(8-3)^2 + (5-1)^2} = \sqrt{5^2 + 4^2} = \sqrt{25+16} = \sqrt{41} \approx 6.403$$
Step3: Calcular perímetro del cuadrado
El perímetro es 4 veces la longitud de un lado:
$$P = 4 \times \sqrt{41} \approx 4 \times 6.403$$
