Question

Find the area of a square whose one side is
a 3 cm​

Answer 1

Answer:

area of square =side ×side

area=3cm×3cm

area=9cm²

Answer 2

Answer:

Hence the area of a square is $9cm^2.$

Step-by-step explanation:

According to the data given in the question,

It is given that, the side of a square is $3$ 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= $3$ cm,

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

${\text } A = (3)^2$

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

${\text } A = 3\times 3$

${\text } A = 9cm^2$

Hence the area of a square is $9cm^2.$
