Answer:
15 units^2
Explanation:
If we plot our points, we will notice that it is a triangle
The formula for area of a triangle is 1/2 * b * h
Our base will be 6, as the distance along the x-axis from (0,5) to (6,5) is 6 units
Our height will be 5 as the distance from (3,5) to (3,0) is 5
5*6 = 30
30/2 = 15
So 15 units^2
Best of luck
