So the formula for the area of a triangle is [tex] A=\frac{1}{2} bh [/tex] (b = base, h = height). In this case, by counting from (-3,-3) to (-3,2) the height is 5 and the base is 4 counting from (-3,2) to (1,2).


Using this info, we can form the equation[tex] A=\frac{1}{2} *4*5 [/tex] and solve from there.


[tex] A=\frac{1}{2} *4*5\\ A=\frac{1}{2} *20\\ A=10 [/tex]

Plot the vertices, and you'll see that the triangle is a right triangle with one vertical side and one horizontal side.


Area of a triangle = (1/2) x height x base, so in this case,


Area = (1/2) x 5 x 4


Area = 10
