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! 🙂
