The area of a rectangle is given by:
[tex]\begin{gathered} A=w\cdot h \\ \text{Where:} \\ w=\text{width} \\ h=\text{height} \end{gathered}[/tex]A. The height could be 1 and the width 12
[tex]\begin{gathered} 12=12\cdot1 \\ 12=12 \end{gathered}[/tex]This is a correct choice
B. The height could be 8 and the width 4
[tex]\begin{gathered} 12=4\cdot8 \\ 12\ne32 \end{gathered}[/tex]This is an incorrect choice
C. The height could be 3 and the width 4
[tex]\begin{gathered} 12=4\cdot3 \\ 12=12 \end{gathered}[/tex]This is a correct choice
D. The height could be 6 and the width 2
[tex]\begin{gathered} 12=2\cdot6 \\ 12=12 \end{gathered}[/tex]This is a correct choice
