Question

find the area of the square whose side are 2.5cm​

Answer 1

Area of square = side × side

= 2.5 × 2.5

= 6.25 sq. cm

Answer 2

Answer:

Hence the area of a square is $6.25cm^2.$

Step-by-step explanation:

According to the data given in the question,

It is given that, the side of a square is $2.5$ 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= $2.5$ cm,

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

${\text } A = (2.5)^2$

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

${\text } A = 2.5\times 2.5$

Multiply $2.5$ and $2.5$, we get

${\text } A = 6.25cm^2$

Hence the area of a square is $6.25cm^2.$
