Question

What is the area of the triangle in the coordinate plane?

Answer 1

Answer:

The area of the triangle is $16\ units^{2}$

Step-by-step explanation:

we know that

The area of a triangle is equal to

$A=\frac{1}{2}bh$

where

b is the base of triangle

h is the height of triangle

In this problem

Observing the graph

$b=(12-8)=4\ units$

$h=(10-2)=8\ units$

substitute the values

$A=\frac{1}{2}(4)(8)=16\ units^{2}$

Answer 2

To solve for the area of a triangle you use the formula A=b*h/2. The base for this triangle is 4 and the height is 8. Take 4*8 which is 32 and divide that answer in half to get 16 which is your answer.
