55 over 3, or 55 wrestlers for every 3 rounds, but the wrestlers value is negative, thus 55 "less" wrestlers for every 3 rounds on average.
Answer/Step-by-step explanation:
Area of a rectangle = Length × Width
Width of the large rectangle = a
Length of the large rectangle = (2 + 3 + 4)
Therefore:
Area of the large rectangle = a(2 + 3 + 4)
Hope this helps you...!!!
