Question

Find the area of the square whose side is 9cm​

Answer 1

Answer:

81cm^2

Step-by-step explanation:

side=9cm

area of square= s*s= 9*9= 81cm^ 2

Answer 2

Answer:

Hence the area of a square is $81cm^2.$

Step-by-step explanation:

According to the data given in the question,

It is given that, the side of a square is $9$ cm,

We have to find the area of a square,

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

The area is equal to side square, i.e. ${\text } A = a^2$

Where a is the side of the square,

Given: a= $9$ cm,

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

${\text } A = (9)^2$

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

${\text } A = 9\times 9$

${\text } A = 81cm^2$

Hence the area of a square is $81cm^2.$
