Answer:
A. 78
Step-by-step explanation:
Given image can be re-drawn as (see the attachment)
Now, we need to calculate Area I and Area II
So Area I will have length as [tex]8+3=11\ inches[/tex].
And width as [tex]6\ inches[/tex]
Area I
[tex]=length\times width\\=11\times6=66\ inch^2[/tex]
Also, Area II will have length a [tex]10-6=4\ inches[/tex]
And width as [tex]3\ inches[/tex]
Area II
[tex]=length\times width\\=4\times3=12\ inch^2[/tex]
Total area of the diagram would be sum of Area I and Area II
So, [tex]66+12= 78\ inch^2[/tex]
