Question

me ajudem, por favor​

Answer 1

$Base = \sqrt{2} + 3\\Altura = 3\sqrt{2} - 2 \\Area = Base * Altura\\Area = (\sqrt{2} + 3) * (3\sqrt{2} - 2)$

Com a distributiva:

$Area = (3\sqrt{2} * \sqrt{2}) - (2 * \sqrt{2}) + (3 * 3\sqrt{2} ) - (2 * 3)\\Area = (3\sqrt{2 * 2}) - 2\sqrt{2} + (9\sqrt{2} ) - 6\\Area = (3\sqrt{4}) - 2\sqrt{2} + (9\sqrt{2} ) - 6\\Area = (3 * 2) - 2\sqrt{2} + (9\sqrt{2} ) - 6\\Area = 6 - 2\sqrt{2} + 9\sqrt{2} - 6\\Area = - 2\sqrt{2} + 9\sqrt{2}\\Area = 9\sqrt{2} - 2\sqrt{2}\\Area = 7\sqrt{2}$
