"To get an age in years, we use radiometric dating of the rocks. Not every rock can be dated this way, but volcanic ash deposits are among those that can be dated. The position of the fossils above or below a dated ash layer allows us to work out their ages. The volcanic ash layer is dated as 507 million years old."

Answer: $42 units^{2}$

Explanation:

We can divide this figure in a rectangle with base $b=1 unit$ and height $h=12 units$ ; and a right triangle with base $B=5 units$ and height $H=12 units$ .

Now, the total area $A$ of the figure will be the area of the rectangle $A_{rectangle}$ plus the area of the triangle $A_{triangle}$ :

$A=A_{rectangle}+A_{triangle}$

Where:

$A_{rectangle}=(b)(h)=(1 unit)(12 units)=12 units^{2}$

$A_{triangle}=\frac{(B)(H)}{2}=\frac{(5 units)(12 units)}{2}=30 units^{2}$

Then:

$A=12 units^{2}+30 units^{2}$

$A=42 units^{2}$ This is the area of the figure

What where is the NYC Empire State Building located?

inn [45]

The NYC Empire State Building is a 103-story building located in NYC, which is short for New York City. It was, for a long time, the tallest building in the world.
The address, if that's what you need, is 350 5th Ave, New York, NY 10118, United States of America. The coordinates are 40.748107, -73.985372. The nearest subway station is 34th St & Herald Square, which you can reach via lines B,D,F,M,N,Q, and R, some of which are orange and some yellow, not sure if that makes a difference since I'm not familiar with the NYC subway system, but if you need directions it should help to know that.
