Question 6 On 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. What is the perimeter of the border?Let's assume a standard A4 page size (21cm × 29.7cm). Step 1: Find the dimensions of the inner border rectangle. Border Length = 21cm - 1.5cm - 1.5cm = 18 cm Border Breadth = 29.7cm - 1cm - 1cm = 27.7 cm Step 2: Calculate the perimeter of the border. Perimeter = 2 × (Length + Breadth) = 2 × (18cm + 27.7cm) = 2 × 45.7cm = 91.4 cm
