Answer:
1. b = 2A/h
2. h = 2A/b
Explanation:
All you have to do is isolate the variable.
1.
Isolate b:
A = 1/2 x b x h
Multiply each side by 2
2A = b x h
Isolate b by dividing both sides by h
b = 2A/h
2.
Isolate h:
A = 1/2 x b x h
Multiply each side by 2
2A = b x h
Isolate h by dividing both sides by b
h = 2A/b
