Question

a man star from the vertex of rectangle of side 30 m 40 m respectly and after completing one round he move to opposite vertex . Q1 find distance cover diagonally .Q2 find displacement cover

Answer 1

Given three of vertices of a parallelogram are A(1,2), B (4,3), C (6,6). Let the coordinates of fourth vertex be D (x, y) In a parallelogram, diagonals bisect each other. Hence midpoint of BD = midpoint of AC Midpoint of line segment joining the points  and  is   4 + x = 7 and   and 3 + y = 8  and y = 5Therefore, the fourth vertex, D is (3, 5). Given three of vertices of a parallelogram are A(1,2), B (4,3), C (6,6). Let the coordinates of fourth vertex be D (x, y) In a parallelogram, diagonals bisect each other. Hence midpoint of BD = midpoint of AC Midpoint of line segment joining the points  and  is   4 + x = 7 and   and 3 + y = 8  and y = 5Therefore, the fourth vertex, D is (3, 5).
