Answer»

Answer:

Step-by-step explanation:

the area of the square is 5*5 = 25

Answer:

the 4 pieces removed are of equilateral triangles of side each 5/3 unit

area of 4 equilateral triangles: 4xv3/4 (5/3)^2 = 4x1.732x25/4x9

4.8 unit or 5 unit appr.

Area of 4 triangles removed = (25√3 / 9) cm^2
