Question
A rectangular frame of size 100 cm (length) x 120 cm
(breadth) is to be surrounded by stickers of 2 cm x 2 cm size. How many stickers would be required for such decoration?Solution
Area of Path = Outer area - Inner area = 104 x 124 - 100 x 120 = 896 , Now no. of stickers = 896/(2 x 2) = 224
