Answer:

31.070 cm

Step-by-step explanation:

The perimeter of a square can be found by multiplying the length of one side by 4. This is because all the sides of a square is considered equal.

Since in this case the side length is unknown, we need to reverse this formula.

Instead of p = 4s, we need to use s = p/4 where s is the side length and p is the perimeter.

The perimeter is 124.28 cm, so all we have to do now is to divide.

s = 124.28 cm / 4

s = 31.07 cm

Before we find the final answer, we need to round this off to the correct number of significant figures, which is 5.

Therefore, the side length of the given square is 31.070 cm.

Hope this helps!

Answer:

31.07 cm

Step-by-step explanation:

Perimeter = 4 × sides

Perimeter given = 124.28 cm

Thus 124.28 cm = 4 × sides

Sides = 124.28 ÷ 4 cm

Sides = 31.07 cm each
