Question

Find the area of the triangle formed by the straight lines, 4x - 3y + 1 = 0, x + 3y – 11 = 0,
2x+y+ 3 = 0​

Answer 1

Answer:

first of all you have to find the points of intersection of these equations after that you will have three points A(x, y) And similaarly B and C now put in area formula which is

absolute of x y 1

x y 1

x y 1 now solve thia determinant....
