S = ah / 2 – we represent the expression on the left side of the equation as a fraction S / 1;
S / 1 = ah / 2 – apply the main property of proportion: The product of the extreme terms of the proportion is equal to the product of the middle terms of the proportion; we have S and 2 – extreme terms, and 1 and ah – middle terms of the proportion;
ah * 1 = S * 2;
ah = 2S;
h = 2S: a;
h = 2S / a.
Answer. 2S / a.
