Answer -
(i) Given (3, 8), (-4,2) and (5, -1) are the vertices of the triangle.
We know that, ifvertices of a triangle are (x1, y1), (x2, y2)and (x3, y3), then the area of the triangle is given by:
(ii) Given (2, 7), (1,1) and (10, 8) are the vertices of the triangle.
We know that ifvertices of a triangle are (x1, y1), (x2, y2)and (x3, y3), then the area of the triangle is given by:
(iii) Given (-1, -8),(-2, -3) and (3, 2) are the vertices of the triangle.
We know that ifvertices of a triangle are (x1, y1), (x2, y2)and (x3, y3), then the area of the triangle is given by:
As we know area cannotbe negative. Therefore, 15 square unit is the area
Thus area of triangleis 15 square units
(iv) Given (-1, -8),(-2, -3) and (3, 2) are the vertices of the triangle.
We know that ifvertices of a triangle are (x1, y1), (x2, y2)and (x3, y3), then the area of the triangle is given by:
