Answer 2

Answer:

The area of the square will be $900cm ^2$.

Step-by-step explanation:

In context to questions

We have to find the area of the square,  

As per questions  

We have

The side of a square is $30cm$,  

Here we have to use the formula of area of a square,

The area is equal to side square,

i.e. $A = (side)^2$

 Substitute the value in the formula of area of a square, we get

$A = (30) ^2$

Squaring a number is to multiply the number by itself we get,

$A = 30 \times 30$

$A = 900 cm^2$

Hence, the area of the square is $900cm ^2$.
