Thanks. But the question is asking for the area of the shaded triangle, not length of BC.
Oh sorry my bad, I didn't read the question properly. I calculated it and the answer is 105.3 using Heron's formula which I don't think you guys learnt it
Thank you for helping. We didn’t learn heron in school, but we learn to solve these kind of questions using tricks, maybe it’s one of those. Hope someone can show us some magic.
Ahh I see, I'm really sorry again and I hope so too!
