Question

Hello! I need some help with this question please, thank you in advance. (This is not from an active test, it is from a book I am studying to take the army ASVAB.)

Answer 1

The area of a rectangle is given as:

$A=l\times w$

The area of the frame is given as the area of the rectangle with dimension ( 10 by 8) minus the area of the rectangle with dimension ( 8 by 4)

Therefore

$\begin{gathered} A_1=10\times8=80 \\ A_2=8\times4=32 \\ A_T=80-32=48 \end{gathered}$

Hence, the area of the frame is 48

Option C is correct
