What is the area of the triangle whose vertices are d( 3, 3), e(3, -1), and f(-2, -5)? show all your work! your choice of method on how to find the area.

Answer-

Area of the triangle is 10 sq.units

Solution-

We know that,

Taking,

(x₁, y₁) = (3, 3)

(x₂, y₂) = (3, -1)

(x₃, y₃) = (-2, -5)

Then putting these in the formula,

As area can not be negative, ignoring negative sign,

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
