20 metresA square has 4 equal sides. So for side L, the perimeter P = 4L.
But we know L^2= 25 square metres
Therefore L = ±5 metres.
As a negative length has no physical meaning we ignore L = -5
We insert the value of L = 5 in the equation P = 4L, and arrive at P = 20 metres.

Why are you trying to make it hard for us?
We don't need algebra to solve this.
If area = 25 sq m. One side = √25 = 5 m length of one side.
Since a square has 4 sides, its perimeter = 4(5) = 20 meters.

permit the fringe of the sq. be x m, so, through fact the section, A, is 25m^2, then: A = x^2, so 25 = x^2, so x = rt25, so x = 5. the fringe is 4x = 4 x 5 = 20 m. in basic terms a small element: "the component to a sq. is 25 squareM, or m^2 metres is a linear length.

x^2 = 25
x = √25
x = 5
Perimeter of the square:
4x
= 4(5)
= 20 meters
x = √25
x = 5
Perimeter of the square:
4x
= 4(5)
= 20 meters

Area=(one side)^2
One side=(25)^1/2=5meters
perimeter=4 x 5=20meters
One side=(25)^1/2=5meters
perimeter=4 x 5=20meters

A=25
A=side squared
side = square root of 25
Perimiter= side + side + side + side
Perimeter = 20
i'm sure you can throw a variable in there somewhere.

The area of a square is 25 meters.
Area of a rectangle is width times height (w*h=A).
For a square, w=h, so w=h=sqrt(25)=5.
The perimeter is all sides added to eachother, so w+w+h+h=20 meters.

Area of the square is a^2 = 25 meters squared
each side is then 5
Perimeter = 4*a = 4*5 = 20 meters
each side is then 5
Perimeter = 4*a = 4*5 = 20 meters

s=side, s^2 =area 4s=perimeter
