Multiple Choice

Given the formula: $A = \frac { 1 } { 2 } h ( a + b ) , A = 2,690 , \quad h = 62 , \quad a = 43.2$ Find b.

A) $b = \frac { A } { h } - 2 a = - 43$
B) $b = \frac { A } { 2 ( h - a ) } = 10.9$
C) $b = \frac { A } { 2 ( h - a ) } = - 10.8$
D) $b = \frac { 2 A } { h } - a = 43.6$
E) $b = \frac { A } { 2 h } - a = - 21.5$
