Given triangle XYZ with vertices
X(-2,0),Y(6,0), and Z(4,8), find the number of square units in its area.

  • algebra - ,

    Since two points lie on the x-axis, this becomes an easy question
    Consider XY as the base, its length would be 8
    Z is 8 units above the x-axis, so the height is 8

    Area = (1/2)base x height
    = (1/2)(8)(8) = 32
