Answer 2

Answer:

Step-by-step explanation:

From the square of side only right triangles can be removed to form a regular octagon.

Let the side of the triangle =x

Then the hypotenuse of the triangle so removed equals √(x²+x²)=√2 x

This forms the side of the octagon

Length of the side of the square remaining after removing the triangular edges=5–2x

Since all sides of regular hexagon are equal

Hence 5–2x=√2 x

Or √2 x+2x=5

Or (√2 +2)x=5

and x=5/(√2 +2)

Area removed from one corner =(1/2)x²= (1/2{5/(√2 +2)²

Area removed from four corners =(1/2)x²= 4×(1/2{5/(√2 +2)² }= 2{5/(√2 +2)}²= 4.29 square units (approx)
