how do i do this problem?

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.
