If the coordinates of the centroid, orthocenter and circumcentre of a triangle are (0,a) ; (0,b) & (0,c) respectively, what is the area and perimeter of the triangle?

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

I also faced this same doubt..as far as i think..there can be more than one triangle..with different areas ..but having the same set of circumcentre orthocentre & centroid..am i right?@Pi Han Goh

How are the "centroid, orthocenter and circumcentre" are related to each other?
If we know that already, can we related "b" and "c" to "a" (and vice versa)? Can we actually solve for these values?

Instead of asking me questions, why don't you show your work and where you're stuck, so that I can identify where your issue is.
