Answer:
6 in²
Step-by-step explanation:
The formula of an area of a triangle:
[tex]A_\triangle=\dfrac{bh}{2}[/tex]
b - base
h - height
We have the right triangle. One leg is a base and other leg is a height.
Therefore
b = 3in, h = 4in.
Substitute:
[tex]A_\triangle=\dfrac{(3)(4)}{2}=\dfrac{12}{2}=6\ in^2[/tex]
