The formula for area of a triangle is
Area= 1/2*base*height
If you substitute values in for the base and height, you get the equation
Area = 1/2*14*9
When you multiply 1/2 by 14, you get 7. Substitute for this in your equation.
Area=7*9
Simplify by multiplying 7*9=63.
The area of the triangle is 63 inches.
