Multiple Choice

Given the formula: $A = \frac { 1 } { 2 } h ( a + b ) , \quad A = 6,309 , \quad h = 13.0 , \quad b = 546$ Find a.

A) $a = \frac { A } { 2 h } - b = - 303$
B) $a = \frac { 2 A } { h } - b = 425$
C) $a = \frac { A } { 2 ( h - b ) } = 27$
D) $a = \frac { A } { 2 ( h - h ) } = 106$
E) $a = \frac { A } { h } - 2 b = - 607$
