Answer» 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/=450 x 350/= 63 Square area=50 x 50. Wall can be covered only by using square sized wallpaper pieces.
