Question

Find the perimeter of a square whose area is 625 cm how to solve it without square root

Answer 1

let the number be x .
area= sXs
xXx=x2

but the area is given which is equal to 625 CM .
x to the power 2 is equal to 625.

${x }^{2} = 625$
$x = \sqrt{625}$
$x = 25$
the sides are 25 CM.
therefore perimeter
$= 25 \times 4$
=100
