Answer:

10 m

Step-by-step explanation:

A square has all equal side lengths. If that is the case, the we have 4 sides that equal each other:

x + x + x + x = 40 m

4x = 40m

x = 10m

So each side is 10 m long.

Answer: Each side is 10 m

Step-by-step explanation: The perimeter is the total length of all the sides.

A square has 4 equal sides, so you divide the perimeter by 4.

40m÷4 = 10m
