Step-by-step explanation:
Length= 8cm, breadth= 5cm
Area of the cupboard= l\times b
=8cm\times5cm=40cm^2
Width of the margin= 1.5cm
Length of the cardboard
=8cm-1.5\times2cm
=8cm-\ 3cm=5cm
Breadth of the inner cardboard
=5cm\ -\ 1.5\times2cm
=5cm-3cm=2cm
Area of the inner rectangle= l\times b
=5cm\times2cm=10cm^2
Area of the margin
=40cm^2-10cm^2=30cm^2
Hence the required area= 30cm^2
