Assuming that the covers are of circular shape,the maximum diameter is 5 cm.Area of the circular sheet is πr^2 that is 3.14x2.5x2.5=19.625 cm^2
area of the square=25 cm^2.So area of wasted material is 25-19.625=5.375cm^2.
area of the square=25 cm^2.So area of wasted material is 25-19.625=5.375cm^2.
