The figure is a triangle-We know that the area of the triangle whose vertices are -x1-y1-x2-y2- and -x3-y3- is 12-x1-y2-x2212-y3-x2-y3-x2212-y1-x3-y1-x2212-y2-Therefore-xA0-Area -12-3-0-x2212-4-5-4-x2212-0-0-4 square units-

Plot (3,0),(5,0) and (0,4) on cartesian plane. Name the figure formed by joining these points and find its area.Figure formed is a Rectangle and Area =52 sq. unitFigure formed is a square and Area =40 sq. unitFigure formed is a triangle and Area =4 sq. unitNone of these

The figure is a triangle.We know that the area of the triangle whose vertices are (x1,y1),(x2,y2), and (x3,y3) is 12|x1(y2−y3)+x2(y3−y1)+x3(y1−y2)|Therefore, Area =12[3(0−4)+5(4−0)+0]=4 square units.

Plot $(3, 0), (5, 0)$ and $(0, 4)$ on cartesian plane. Name the figure formed by joining these points and find its area.
Figure formed is a Rectangle and Area $= 52$ sq. unit
Figure formed is a square and Area $= 40$ sq. unit
Figure formed is a triangle and Area $= 4$ sq. unit
None of these
