@engineers_feed 49 is the answer
Area of the traingle is 150 ×4 =600
Area of the big square =625
625-600=25,
The triangles are over laped and covered 6 area each so 4×6 =24
This will be added to the 25 which is 49
The area of small square is 49
Personally for me, the fact that we are all going to die someday is the most powerful reason to stay humble and not hate anyone. I think we should use this temporary existence of ours to spread positivity & hope instead of creating fear and breeding enmity between people.
When I started focusing on my own peace of mind after failed UPSC attempts, the unexpected benefits were I started forgiving people instantly and forgetting unpleasant experiences easily. In turn it made me calm and peaceful. This works almost every day.
