Question

2. What is the perimeter of the square in the diagram? A 12 cm B 16 cm C 24 cm D 36 cm 36 cm²

Answer 1

The perimeter is the sum of all sides of the square.

We need to find the length of the sides first. Since the area is 36m², we can conclude that length of one side s, is equal to:

$\begin{gathered} s=\sqrt[]{36} \\ s=6 \end{gathered}$

Therefore, the perimeter is:

$\begin{gathered} P=s+s+s+s \\ P=4s \\ P=4\cdot6 \\ P=24\operatorname{cm} \end{gathered}$

Answer:

C) 24 cm
