Question

Find the perimeter of a square whose area is 625 cm square
With explanation please

Answer 1

Answer:

100 cm

Step-by-step explanation:

Let the length of the side be x.

Then, x²=625

x=√625

x=±25 cm

As, lengths can't be negative, x=25 cm.

Perimeter=4*x

=4*25

=100 cm

Hope it helps

Answer 2

Answer:

area of square is given by- a^2 where 'a' is the length of the side

hence square root of the area will give the length of the side

a^2=625

therefore a=25cm

perimeter if the square is given by 4(a) where 'a' is the length of the side

hence perimeter is

4(25)= 100cm
