Answer :

48 sq.cm

Solution :

Side of an outer square sheet =8cm

Area of an outer square =82=64sq.cm

Width of a removed piece of paper =2cm

Side of the inner square =8−2(2)=8−4=4cm

Area of the inner square =42=16sq.cm

Area of the removed paper =Area of the outer square -Area of the inner square

64−16=48sq.cm
