A rectangle ABCD is 20 cm long and 10 cm wide. There is a border towards the inner side of the rectangle that is 2 cm wide. Find the area of the border?

108 cm²

104 cm²

96 cm²

None of these

To find the area of the border, let's first find the area of the entire rectangle and the area of the inner rectangle.

Area of entire rectangle = Length × Width

= 20 × 10

= 200 cm²

The inner rectangle's dimensions are:

Length = 20 - 2 × 2 = 16 cm

Width = 10 - 2 × 2 = 6 cm

Area of inner rectangle = 16 × 6

= 96 cm²

Area of border = Area of entire rectangle - Area of inner rectangle

= 200 - 96

= 104 cm²
