Question

A square field has an area 625cm. Find the length of one of side.​

Answer 1

Answer: 25cm

Step-by-step explanation:

Since the field is square we can understand each side is an equal length

This means we just have to use the formula...  

$A^2 = 625$

$\sqrt{a^2} = \sqrt{625}$

a = ±25

Since it is a real thing, we are only looking at positive values, therefore your answer is

25cm
