Answer 8

The area of a square is the square of the length of a side.
That means the side is the square root of the area.
You know the area is 25 m^2.
Square root of 25 m^2 will give you one side.
4 times one side is the perimeter.

Answer 9

A 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

Answer 10

So it's 25 @mathstudent55

Answer 11

@mathstudent55 it will be 20

Answer 12

One step at a time.

A = 25 m^2

\(Side = \sqrt{25~m^2} \)

What is the length of the side?

Answer 13

5

Answer 14

umm 5?

Answer 15

Correct, 5 m.

Next step, since a square square has 4 sides of equal length, the perimeter is simply 4 times the length of one side.

\(P = 4s = 4 \times 5 ~m = \)?

Answer 16

20

Answer 17

20

Answer 18

Correct, 20 m.
