The height is 50m, since all the lines are perpendicular
drawing a straight line PB from P perpendicular to AB will be 20+30=50
$$answer=option\ E$$

\[? = {\text{dist}}\left( {P,\overleftrightarrow {AB}} \right)\]
Important: the distance between a given straight line r and a given point P that does not belong to r is
equal to the length of the line segment PQ, where Q is the intersection of r and the perpendicular
to this line that passes through P (see figure, in this case Q=B).

$$? = 30 + 20 = 50$$

This solution follows the notations and rationale taught in the GMATH method.
