Question

If one side of the square is 15 cm . Find its area

and perimeter​

Answer 1

Answer:

Perimeter = 60 cm , Area = 225 cm²

Step-by-step explanation:

Length of the square , l = 15 cm

Perimeter of the square, p = 4 × l

= 4 × 15 cm

= 60 cm

Area of the square = ( side )²

= 15² cm

= 225 cm²

Answer 2

Given :

• Length of each side of square = 15 cm

To find :

• Area of square
• perimeter of square

Formula used :

• Area of square = a²

• perimeter of square = 4a

where a is length of each side of square.

Solution :

Length of each side of square = 15 cm

$Area \: of \: square = a²$

put a = 15

$\implies \: Area \: of \: square = (15)²$

$\implies \: Area \: of \: square = 225 {cm}^{2}$

Now :-

$perimeter \: of \: square = 4a$

$\implies \: perimeter \: of \: square =( 4 \times 15)$

$\implies \: perimeter \: of \: square = 60cm$

Answer :

• Area of square = 225 cm²

• perimeter = 60 cm
