Question

Each student in a class room has a rectangular desk that measures 60 cm by 45cm .Some of these desks are put together as shown in the figure to form a large square table for a class activity.

a)Find the least length of a side of the square .

b)and the number of rows and colums of desk used to form the large square table.​

Answer 1

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= $\frac{180}{60}$

         = 3

 

Answer 2

Answer:

180 cm the answer is a question 180cm
