Let Side = a, Daignol = root(2)a

Each side of EFGH = a/2root(2)

Area of EFGH = a/8.

Let total Area of the square is 8

area of Triangle AGD is one fourth of total area.

so area is of triangle is 2.

area of EFGH is 1.

now calculate percentage area by dividing 1by 8 multiple by 100.

which is 25/2
