Question: what is the formula for area of triangle in coordinate geometry?
Answer: The first formula most encounter to find the area of a triangle is A = 1⁄2bh. To use this formula, you need the measure of just one side of the triangle plus the altitude of the triangle (perpendicular to the base) drawn from that side. The triangle below has an area of A = 1⁄2(6)(4) = 12 square units.
