Use Heron's Formula:
s means semi-perimeter = (50 + 31 + 18) / 2 = 99 / 2 =
49.5
area = sq root [(s * (s-a) * (s-b) * (s-c)]
area = sq root [(49.5 * (s-a) * (s-b) * (s-c)]
This will NOT form a triangle. The longest side (50) is greater than the sum of the other 2 sides.

Answer:
7.07 units
Step-by-step explanation:
Use the Pythagorean theorem for the right triangle:

If a = x, b = x, and c = 10, then

17+4=21
21 divided by 3= 7
17 dollars for tickets
21-4=17
so your answer is 21 he has to sweep the floor 21 times to get tickets
Its 9-1 so that would be 8 idk if you are right just noticed and though it would help
