Answer 2

Answer:

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

Step-by-step explanation:

As per the data given in the above question,

The given data is the side of a square is 9cm,

We have to find the area of the square,

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

Area =$a^{2}$

Where a is the side of a square,

Substitute the value of side given, in above area formula we get,

$A=9^{2}$

Squaring a number is to multiply a number by itself,

$A=9\times 9\\A=81cm^{2}$

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