If you mean vertices of: (-1, -1) (-1, 3) and (5, -1) then when plotted on the Cartesian plane it will form a right angle triangle with a base of 6 units and a height of 4 units.
Area of triangle: 0.5*6*4 = 12 square units

How can you find the area of a triangle whose vertices are 4 0 0 6 and 0 0?
The base of the right-angled triangle = 4 units The height = 6 units The area = 0.5 * base * height = 12 square units =========================
What is the area of a triangle whose base is 10 centimeters and whose height is 20 centimeters?
The area of triangle is : 100.0
How do you find the area of triangle using given coordinates?
Simple. Just multiply the base by the height of the triangle, and divide it into two. This works for all types of triangles.
There is a right triangle whose hypotenuse is 2009 The two legs of the triangle are both whole numbers Computer the area of this unique triangle?
432180. The legs are 441 and 1960.
What is area of equilateral triangle whose side is 7 cm?
A triangle with side a: 7, side b: 7, and side c: 7 cm has an area of 21.22 square cm.
How do you find the area of a polygon using its vertices?
Select any one of the vertices and draw all the diagonals from that vertex. This will divide the polygon (with n sides) into n-2 triangles. Use the coordinates of the vertices of each triangle to calculate its area, and then add the areas of these triangles together.
What is the area of the triangle ABC with vertices A at -1 4 B at 1 -2 and C at 5 1?
The area is calculated easily using the determinant of the matrix of coordinates, or Heron's formula and is 15 square units.
