Question

find the are of square whose side is 7 cm​

Answer 1

Answer:

49

Step-by-step explanation:

area of a square =a^2

                            =7^2

                            =49sq.cm

Answer 2

Answer:

Hence the area of a square is $49cm^2.$

Step-by-step explanation:

According to the data given in the question,

It is given that, the side of a square is $7$ 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= $7$ cm,

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

${\text } A = (7)^2$

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

${\text } A = 7\times 7$

${\text } A = 49cm^2$

Hence the area of a square is $49cm^2.$
