Answer:

square root of 405

Step-by-step explanation:

We notice that the area is 9 yards in height and 18 yards in length and we can use the pythagorean theorem which is the square root of x^2+y^2. X being 18 and y being 9 that gives us 81+324, which equals 405. so the answer is the square root of 405.

81 should be your answer you take length times height then divide by two because it’s a triangle
