  1. a) 180 cm
    b)  3 columns and 4 rows.
    Step-by-step explanation:
    One side must be multiples of 45 and other side 60 and both sides should be equal.
    i.e. 45 columns = 60 Rows
    //Find the GCF.
    GCF of 45, 60 = 15.
    So for 3 columns of one side, you will need have 4 rows of other side to make the lengths equal
    the least square of side that can be formed = 45*4 = 60*3 = 180cm
    b) the number of rows and columns to form the desk would be 4 rows and 3 columns
