may it’s help you all the best

Length of board = 40cm

Breadth of board = 3cm

Area of drawing board = l x b

= 40 x 3 = 120 sq. cm

Length of side of border = 4cm

Area inside the border = side x side

= 4 x 4 = 16 sq. cm (as it is a square)

Area of border = area of board – area inside of border = 120 – 16 = 104 sq. cm

Hope this helps you! 🙂
