Answer 2

Answer:

Hence the area of a square is $81\:cm^{2}$

Step-by-step explanation:

According to the question details are as below,

The given detail are side of a square is 9cm,

We have to find the area of a square,

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

Area is equal to side square, i.e.$A=a^{2}$

Where a is the side of the square,

Given a= 9cm,

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

$A=9^{2}$

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

$A=9\times9\\A=81\:cm^{2}$

Hence the area of a square is $81\:cm^{2}$
