Answer:

Choice A

Step-by-step explanation:

A = 1/2 (b1+b2)h

Multiply each side by 2

2A =  (b1+b2)h

Divide each side by (b1+b2)

2A/ ((b1+b2) = h

Answer:

A

Step-by-step explanation:

We have to isolate h on one side.

First, we remove the 1/2 multiplying by H by multiplying both sides by 2

Which results with:

2A = h(b1+b2)

next we have to get rid of (b1+b2) by

dividing both sides by (b1+b2)

2A/(b1+b2)=h
