Question

the area of a square is 25cm2 what is its perimeter

Answer 1

Answer:

20 cm

Step-by-step explanation:

area of square= side × side

25= side^2

side = 5

perimeter of square= 4l

= 4×5

= 20 cm

Answer 2

Given :

• Area of square = 25 cm²

To find :

• Perimeter of square

Formula used :

$\rm A = {a}^{2}$

$\rm P = 4 \times a$

Where :-

• A = area of square
• a = length of each side of square
• P = perimeter of square

Solution :

Area of square is = 25 cm²

Let length of each side of square be x.

Therefore , according to the question :-

=> A = a²

=> 25 = x²

=> √(25) = x

> 5 cm = x

length of each side of square = 5 cm

Now , we will find perimeter of square :-

=> P = 4 × a

=> P = 4 × 5

=> P = 20 cm

Answer :

• Perimeter of square = 20 cm
