Answer:

b_2 = \frac{2A}{h} -b_1

Step-by-step explanation:

Given

A = \frac{1}{2}h(b_1 + b_2)

Required

Select equivalent expressions

Multiply through by 2

2*A = 2*\frac{1}{2}h(b_1 + b_2)

2*A = h(b_1 + b_2)

2A = h(b_1 + b_2)

Divide through by h

\frac{2A}{h} = \frac{h(b_1 + b_2)}{h}

\frac{2A}{h} = b_1 + b_2

Subtract b1 from both sides

\frac{2A}{h} -b_1= -b_1 + b_1 + b_2

\frac{2A}{h} -b_1=  b_2

b_2 = \frac{2A}{h} -b_1

<em>From the list of options, there is only one answer</em>
