Question

find the area of a square whose side is 4.5cm



​

Answer 1

Answer:

area of square=S×S

=4.5cm×4.5cm

=20.24cm²

Answer 2

Answer:

Hence the area of a square is $20.25cm^2.$

Step-by-step explanation:

According to the data given in the question,

It is given that, the side of a square is $4.5$ 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= $4.5$ cm,

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

${\text } A = (4.5)^2$

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

${\text } A = 4.5\times 4.5$

Multiply $4.5$ and $4.5$ we get

${\text } A = 20.25cm^2$

Hence the area of a square is $20.25cm^2.$
