Find the area of triangle having vertices A(-1,5) , B(-2,6) and C(3,5)
draw the triangle!
It has base 4 and height 1
C'mon, guy, you know this stuff.
To find the area of a triangle with given vertices, you can use the formula for the area of a triangle using coordinates.
The formula to calculate the area of a triangle with vertices (x1, y1), (x2, y2), and (x3, y3) is:
Area = 1/2 * |(x1*(y2-y3) + x2*(y3-y1) + x3*(y1-y2))|
In this case, let's substitute the given coordinates into the formula.
A(-1, 5), B(-2, 6), C(3, 5)
Area = 1/2 * |(-1*(6-5) + -2*(5-5) + 3*(5-6))|
Simplifying the equation:
Area = 1/2 * |-1 + 0 - 3|
Area = 1/2 * |-4|
Area = 1/2 * 4
Area = 2
Therefore, the area of the triangle with vertices A(-1, 5), B(-2, 6), and C(3, 5) is 2 square units.
