Question

4. Find the area of a square whose side is 12 cm.​

Answer 1

area = side × side

area= 12×12=144cm^2

so your ans is 144cm^2

Answer 2

Answer:

Hence the area of a square is $144cm^2.$

Step-by-step explanation:

According to the data given in the question,

It is given that, the side of a square is $12$ 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= $12$ cm,

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

${\text } A = (12)^2$

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

${\text } A = 12\times 12$

${\text } A = 144cm^2$

Hence the area of a square is $144cm^2.$
