Question

What is the perimeter of a 10cm square tile?

Answer 1

Answer:

40cm

Explanation:

A square has 4 equal sides, therefore:

$\begin{gathered} \text{Perimeter}=4s \\ s=\text{side length} \end{gathered}$

Given a 10cm square tile:

$\begin{gathered} \text{Perimeter}=4\times10 \\ =40\operatorname{cm} \end{gathered}$

The perimeter of a 10cm square tile is 40cm.
