In an isosceles trapezoid, the bases are 3 and 9 and one of the angles between the side and the base is 45 degrees, find the area of the trapezoid
trapezoid area: half the sum of the bases per height. therefore: S = (3 + 9) / 2 * h = 6h cm ^ 2
what to find the height (h), you need: (9-3) / 2 = 3 cm
in now we just multiply 6 * 3 = 18cm ^ 2
answer: 18cm ^ 2
