What is the side of a square lot with an area of 400 sq. m?

Sagot :

The area of a square is computed as [tex]s^2[/tex] where s is the side length.
So:
[tex]400=s^2 \\ 20=s[/tex]

We do not have -20 because there is never a side length that is negative.

Therefore the side length is 20 m.
The formula for the area of a square:
A=s²

Substitute with the given measurements:
400 m²=s²
Square root both sides
s=20 m

It cannot be s=-20 m because there are no negative length. Hope this helps =)
