given, dimensions of cardboard = 12cm×10 cm
dimensions of photo = 8cm×6cm
area of cardboard= 12 ×10 cm^2
120 cm^2
area of photo = 8×6 cm^2
= 48 cm^2
area of visible cardboard = area of cardboard -area of photo
=120 - 48 cm^2
= 72 cm^2
dimensions of photo = 8cm×6cm
area of cardboard= 12 ×10 cm^2
120 cm^2
area of photo = 8×6 cm^2
= 48 cm^2
area of visible cardboard = area of cardboard -area of photo
=120 - 48 cm^2
= 72 cm^2
