Answer:
14 centimeters.
Step-by-step explanation:
We can plug in the lengths into [tex]A=\frac{ab}{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] represent the legs: base and height. It would result in [tex]A=\frac{7*4}{2}[/tex]. From there, you would find that seven times four is twenty-eight, and when divided by two it equals fourteen.
The area of a right triangle that has legs seven and four centimeters long is fourteen centimeters.
