A Wall Is 4.5 Meters Long And 3.5 Meters High. Find The Number Of Maximum Sized Wallpaper Squares, If The Wall Has To Be Covered With Only The Square Wall Paper Pieces Of Same Size?

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.
