The Solution:

Given:

We are required to find the area and the perimeter of the given shape.

step 1:

Find the perimeter.

The formula for the perimeter is:

$\begin{gathered} Perimeter=2(L+W) \\ \\ Where: \\ L=length=4.8mm \\ W=width=3.2mm \end{gathered}$

Substitute:

Step 2:

Find the area.

The formula for the area is:

$\begin{gathered} Area=L* W \\ \\ In\text{ this case,} \\ L=length=4.8mm \\ W=width=3.2mm \end{gathered}$

Substitute:

$Area=4.8*3.2=15.36\approx15.4mm^2$

Therefore, the correct answer is [ option B ]
