Hey mate here is your answer...
Length of cloth =30cm
Breadth(width) of cloth =20cm
Area of cloth
= l*b
= 30*20
= 600cm^2
Length of cloth needed for skirt =30cm
Width of cloth needed for skirt =4cm
Area of cloth needed for skirt
= l*b
= 30*4
= 120cm^2
Cloth left
= area of total cloth - area of cloth needed for skirt
= 600 - 120
=480cm^2
Hope this helps.....
