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:
[tex]\begin{gathered} Perimeter=2(L+W) \\ \\ Where: \\ L=length=4.8mm \\ W=width=3.2mm \end{gathered}[/tex]
Substitute:
[tex]Perimeter=2(4.8+3.2)=2\times8=16mm[/tex]
Step 2:
Find the area.
The formula for the area is:
[tex]\begin{gathered} Area=L\times W \\ \\ In\text{ this case,} \\ L=length=4.8mm \\ W=width=3.2mm \end{gathered}[/tex]
Substitute:
[tex]Area=4.8\times3.2=15.36\approx15.4mm^2[/tex]
Therefore, the correct answer is [ option B ]
