Answer:
h = 30 * 2 / 12
h = 5
Step-by-step explanation:
A = b*h / 2
by rearranging this formula we get
h= A*2/b
you can check the solution by putting it in the formula that gives you the area. if it equals 30, it checks out.
pls brainliest (although a second answer is needed to give the crown)
If that is saying 390m tall, cm is a unit of meters, KHDMDCM, so the building is 39,000cm tall. Divide 39,000cm by 30cm, you end up with 1,300 feet. The answer is 1,300 feet
Answer:
