Notice that the figure is a right triangle; therefore, its area is given by the formula
[tex]A=\frac{1}{2}b\cdot h_{}[/tex]
In our case, b=4cm and h=3cm; thus,
[tex]\begin{gathered} \Rightarrow A=\frac{1}{2}\cdot4\cdot3=\frac{1}{2}\cdot12=6 \\ \Rightarrow A=6 \end{gathered}[/tex]
Therefore, the answer is 6 cm^2, the first option (top to bottom)
