Question

The perimeter of a square is 28.2 m . Find it's area ?

Answer 1

Solution :-

Given ,

• Perimeter of square = 28.2 m

We need to find ,

• Area of square = ?

As we know that ,

♦ Perimeter of square = 4 × side

Method of solving :-

• By substituting the value of perimeter of the given square & by simplifying it we can have the value of side . So , as we know that Area of square = Side² , by substituting the value of side we can have the area of square .

Simplification :-

Firstly finding the side :

→ Perimeter = 4 × side

→ 28.2 = 4 × side

[ °.° 4 transposed to RHS to LHS ]

→ 28.2 ÷ 4 = Side

→ Side = 7.05 m

Now , by substituting the value of side in area of square

⇒ Area = Side²

⇒ Area = ( 7.05 )²

⇒ Area of square = 49.7 ≈ 50

Note :- This symbol ‘≈’ means approximate value of that number .

Hence , area of square = 49.7 approximately equal to 50 .

Answer 2

Answer:

$perimeter \: of \: square = 4 \times side$

PERIMETER IS GIVEN 28.2 M

28.2 =4×side

$side = 28.2 \div 4 = 7.05$

hence

$area \: of \: square \: = side {}^{2}$

=7.05×7.05

=49.7025
