    Explanation:
    Wall can be covered only by using square sized wallpaper pieces.
    Different sized squares are not allowed.
    Length = 4.5 m = 450 cm; 
    Height = 3.5 m = 350 cm
    Maximum square size possible means HCF of 350 and 450
    We can see that 350 and 450 can be divided by 50.
    On dividing by 50, we get 7 and 9.
    Since we cannot divide further, HCF = 50 = size of side of square
    Number of squares = Wall area/Square area =(450 x 350)/(50x50)= 63
