Soltuion :
1] Least length of a side of square=180 cm
2] Number of rows = 4
and
Number of columns = 3
As we know to make a square frame, We have to use 60 × 40 desks in a such a manner that both the dimensions becomes equal .
To Find : We must use The LCM Method
1] Least Length of a side of the square ABCD is as follows
ABCD=LCM (60,45)
= 180 cm.
2] Number of rows of the desk used to form square ABCD is as follows :-
= 180/45
= 4
Thus,The number of columns of decks used to form square
ABCD= 180/60
= 3
