We must compute the area of a triangle with vertices:
• P1 = (x1, y1) = U = (-7, -9),
,
• P2 = (x2, y2) = V = (-4, -7),
,
• P3 = (x3, y3) = W = (-6, -6).
The area of a triangle given the coordinates of its vertices is given by the following formula:
Replacing the values of the coordinates in the formula above, we get:
Answer
The area in square units of the triangle UVW is 3.5.
