i don't know what you meant by the queston

Step-by-step explanation:

1).  yes, someone can tell you.

2).  your answer is not right.



the altitude of the triangle is cd (2,0) to (4,2).
its length is the square root of (2-0)² + (4-2)² = √(2² + 2²) = √8  =  2√2

the base of the triangle is ac (6,0) to (1,5).
it's length is the square root of (1-6)² + (5-0)² = √(-5² + 5²) = √(50 = 5√2

the area of the triangle is  (1/2) (base) (height) =
                                            (1/2) (5√2) (2√2) =
                                            (1/2) (10 * 2) =
                                            (1/2) (20)  =  10 units
