Answer: the height of this triangle is 55.4 mm

Explanation:


\displaystyle\\Area\ of\ a\ triangle:\ A =\ (ah)/(2) \\\\Hence,\\

Multiply both parts of the equation by 2:


2A=ah

Divide both parts of the equation by a:


\displaystyle\\(2A)/(a) =h\\\\Thus,\ h=(2A)/(a) \\\\h=(2(227.14))/(8.2) \\\\h=(454.28)/(8,2) \\\\h=55.4\ mm
