Question

Quizplus · Accepted Answer

The area of a triangle with vertices (x1, y1), (x2, y2), and (x3, y3) can be calculated using the formula: Area = 0.5 * |x1(y2-y3) + x2(y3-y1) + x3(y1-y2)|. Substituting the given points, the area is 0.5 * |-1(2+2) + 4(-2+2) + 1(-2-2)| = 0.5 * |-8 + 0 - 4| = 0.5 * 12 = 6 cm².
