A(2,2), B(-1,2), C(-1,-1), D(2,-1) are the vertices of square find its area.
Answers
Step-by-step explanation:
The x-coordinates of the vertices of a square of unit area are the roots of the equation x2−3|x|+2=0 . The y-coordinates of the vertices are the roots of the equation y2−3y+2=0. Then the possible vertices of the square is/are (1,1),(2,1),(2,2),(1,2) (−1,1),(−2,1),(−2,2),(−1,2) (2,1),(1,−1),(1,2),(2,2) (−2,1),(−1,−1),(−1,2),(−2,2)
