in Delta ABC , a line parallel to side BC cuts the side AB and AC at points D and E respectively and also point D divide AB in the ratio of 1 : 4 . If area of Delta ABC is 200 " cm"^2 , then what is the area (in " cm"^2 ) of quadrilateral DECB?

If the middle points of the sides BC,CA and AB of triangle ABC are (1,3),(5,7) and (-5,7), respectively,then find the equation of the side AB.

If the middle points of the sides BC,CA, and AB of triangle ABC are (1,3),(5,7), and (-5,7), respec-tively,then find the equation of the side AB.

If AB, BC, CA are three sides of triangle ABC having length 10,7,8 respectively then the projection of sides AB on BC is
