Answer: 58.5 yards squared
Explanation: To find the area of a triangle, use the formula A=1/2(B*H). In this formula, A represents the total area of your triangle, B represents the length of the base, and H represents the height of the triangle. We can plug in our values and get the equation
A=1/2(13*9)
A=1/2(117)
A=58.5
Don’t forget to add your units! If you’d like you can also find half of the base and multiply that by the height.
