tolong dijawab ya pakai cara.

Anggap AB adalah panjang dan BC adalah lebar.

x[tex]\\ AB = x_{B} - x_{A} \\ AB = 6 - (-2) \\ AB = 8 \\ \\ x_{D} = x_{C} - AB \\ x_{D} = 6 - 8 \\ x_{D} = -2 \\ \\ BC = y_{B} - y_{C} \\ BC = 3 - (-2) \\ BC = 5 \\ \\ y_{D} = y_{A} - BC \\ y_{D} = 3 - 5 \\ y_{D} = -2 \\ \\maka, \\D(-2,-2)[/tex]
