What is the area of the triangle in the diagram?
2 answers:
Answer:
B
Step-by-step explanation:
To calculate the area of this triangle we must use vectors :
- vector1 (x1-0,y1-0)⇒ vector1(x1,y1)
- vector2 (x2-0,y1-0)⇒vector(x2,y1)
Now to calculte the area of this triangle we must apply this relation :
A= (1/2)*║x1y1-x2y2║
- x2≥x1 so ⇒ A=(1/2)*(x2y1-x1y1)
- A= (1/2)*y1*(x2-x1)
Answer:
I think the answer is B. Let me know if im right
Step-by-step explanation:
l*w*1/2 is the same as 1/2*y*(x2-x1)
