Using the formula to calculate the area of the triangle we can find the area of the top of the pizza slice plate.
\(\frac{1}{2} * Base * Height = Area\)
The problem state's that the Base is 9 inches and the Height is 14 inches with this info we can plug it into our equation.
\(\frac{1}{2}*\frac{9"}{1}*\frac{14"}{1} = product\)
\(Product = area\)
\(Area = answer\)
You should be able to take over form here.
