Answer: The area common to both triangle is 31.77 sq. cm.
Step-by-step explanation:
Since we have given that
30-60-90 triangles are placed.
So, the ratio of sides would be
Since Hypotenuse = 12 cm
So, it becomes,
So, Base would be
and Perpendicular would be
So, Area common to the both triangles would be
Hence, the area common to both triangle is 31.77 sq. cm.
