Question

Find the area of square whose side is 19cm.

​

Answer 1

Step-by-step explanation:

Area of the square = Side × side

Area of the square = Side × side

Therefore 19×19 =361 sq.cm

Answer 2

Answer:

Hence the area of a square is $361cm^2.$

Step-by-step explanation:

As per the data given in the question,

It is given that,

The side of a square is $19$ cm,

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= $19$ cm,

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

${\text } A = (19)^2$

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

${\text } A = 19\times 19$

${\text } A = 361cm^2$

Hence the area of a square is $361cm^2.$
