Answer:

A. multiply by 1/2

Step-by-step explanation:

A = 1/2 bh

We want to isolate b

We could divide each side by 1/2

A / 1/2 = 1/2 bh  /  1/2

2A = bh

We could divide by h

A/h = 1/2bh/h

A/h = 1/2 b

We could divide by 1/2h

A / (1/2h) = 1/2 bh  /(1/2h)

2A/h = b

We do not want to multiply by 1/2

1/2A = 1/2* 1/2bh

1/2A = 1/4bh  

This does not help isolate b
