Answer 2

The length of the side is 120 cm or 1.2 m or 0.0012 km.

Step-by-step explanation:

Given : The area of table top is 14400 cm square.

To find : The length of its side in m and km ?

Solution :

The area of the square is $\text{Area}=\text{side}^2$.

The area of table top is 14400 cm square.

$14400=\text{side}^2$

$\text{side}=\sqrt{14400}$

$\text{side}=120$

So, the length of its side is 120 cm.

Convert cm into m and km,

1 centimeter = 0.01 meter

120 centimeter = 1.2 meter

1 centimeter = 0.00001 kilometer

120 centimeter = 0.0012 kilometer
