A page in your book, draw a rectangular border that is 1 cm from the top and bottom and 1.5 cm from the left and right sides.
Reduced Length = Original Length − 2
Reduced Width = Original Width − 3
Perimeter = 2 × (Reduced Length + Reduced Width).
Substitute the original dimensions to find the perimeter of the border.
Class 6 NCERT Ganita Prakash Chapter 6 Perimeter and Area
class 6 Mathematics Textbook Chapter 6 question answer
Let the original dimensions of the page be Length (L) and Width (W).
Reduced dimensions:
Reduced Length = L − 2 (1 cm from top and bottom = 2 cm)
Reduced Width = W − 3 (1.5 cm from left and right = 3 cm)
Perimeter of the border:
Perimeter = 2 × (Reduced Length + Reduced Width)
Substitute the given values of Length and Width to find the final perimeter.
