Question

the the side of square 2.5 CM find its perimeter and area ​

Answer 1

Answer:

10 cm

Step-by-step explanation:

There are 4 sides in a square . a square has exactly same cm at all sides . We will count the sum of all sides . add 2.5 4 times or multiply 2.5 by 4 . We get 10 . So the perimeter is 10

Answer 2

Given:

The side of the square is 2.5cm.

To find:

The perimeter and area of the given square.

Solution:

As we know that the perimeter of a square having side 'a' cm is equal to the sum of all sides. This means,

Perimeter = a + a + a + a = 4a (a square has all sides equal)

Also,

the area of this square is equal to the product of two sides. That is

$= a \times a \: = {a}^{2}$

Now,

according to the question, we have, and

Side of the square = 2.5cm

So,

the perimeter of the square

$= 4 \times 2.5$

$= 10 \: cm$

Area of the square

$= {(2.5)}^{2}$

$= 6.25 \: {cm}^{2}$

Hence, the perimeter and area of the square is 10cm and 6.25 square centimetres respectively.
