Question

find the area of the triangular region whose vertices are the points of intersection of the graphs of 2x+y=5 , y=x-4 and y=5​

Answer 1

Hint: In order to solve this problem, we need to use the formula of area of a triangle using the vertices of the triangle. The formula for the area of the triangle is given by S=12[x1(y2−y3)+x2(y3−y1)+x3(y1−y2)] , where, (x1,y1),(x2,y2),(x3,y3) are the coordinates of the three vertices of the triangle.
