Find the area of a triangle with the given vertices.

part i: graph the following points on the coordinate grid below.
(1, -3), (3, -1), (5, -3)

part ii: find the area of the triangle. show your work.

the area of the triangle is 4 square units.

Step-by-step explanation:

Plotting the points, we can see that the triangle is isosceles lying in the 4th quadrant of graph.

we can break the triangle in 2 similar right angled triangles,

each with base 2 and height 2  units.

area of triangle is given by the formula,

A=

thus, A=

A=2 square units.

there are 2 such triangles,

thus total area is 4 square units.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
