The perimeter of a square is 40 cm. Find each side.

$Test$

Step: 1

Now, we have to find the length of each side (s).

We can rearrange the formula to solve for "s":

⇒ \$s = p/4\$

⇒ \$s = (40)/4\$ = 10

So, each side of the square measures 10 cm.

Explanation:

We need to find the length of each side (s).

The formula can be rearranged to solve for "s": \$s = p \times 4\$

For example, if p = 40, then s = 10.

Therefore, the length of each side of a square is 10 cm.
