Question

Find the area and perimeter of a square whose side is 2.8 m​

Answer 1

Answer:

area =s×s

=2.8 × 2.8

=7.84

perimeter=4×s

=4×2.8

=19.2

Answer 2

Answer :-

• The perimeter of the square = 11.2 m.
• The area of the square = 7.84 m².

Given :-

• The side of a square is 2.8 m.

To find :-

• It's perimeter and area.

Step-by-step explanation :-

• Here the side of a square has been given to us. We have to find it's perimeter and area.

--------------------------------

• Let's find the perimeter of the square first!

We know that :-

$\underline{ \boxed{\sf Perimeter \: of \: a \: square = 4 \times Side}}$

Here,

• Side = 2.8 cm.

Hence,

$\rm Perimeter = 4 \times 2.8$

Multiplying 4 with 2.8,

$\rm Perimeter = 11.2 \: m$

--------------------------------

• Now let's find the area of the square!

We know that :-

$\underline{ \boxed{ \sf Area \: of \: a \: square = Side \times Side}}$

Here,

• Side = 2.8 m.

Hence,

$\rm Area = 2.8 \times 2.8$

Multiplying 2.8 with 2.8,

$\rm Area = 7.84 \: {m}^{2}$
