Question

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

Answer 1

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.

Answer 2

The area of the triangle is
`16\ units^(2)`

Explanation:

we know that

The area of a triangle is equal to

`A=(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=(1)/(2)(4)(8)=16\ units^(2)`
