Base of Triangle, b = 2√3
Height of Triangle, h = 3√3
Formula for Area of Triangle, A = (b * h)/2
Area of the Triangle = (2√3 * 3√3)/2
= (2 * √3 * 3 * √3)/2
Collect like terms in the bracket
= (2 * 3 * √3 * √3)/2
= [(2 * 3) * (√3 * √3)]/2
= (6 * 3)/2
= 18/2

Answer:
The layer that contains the youngest fossils is layer A.
Explanation:
In the picture, we have presented four layers and each of them contains one fossil. The rock layers are horizontally arranged and there isn't any disturbance to the layers. Without having disturbances, we have a situation of superposition, basically meaning that the rock layers are arranged in order by age.
The principle of superposition means that the bottom layer of rock strata is the oldest, while the top layer of rock strata is the younges, and all layers between them are arranged from top to bottom as younger to older. In this case, layer A is the one on top, thus it is the youngest layer of rock, and with it, the fossils it contains are the most recent as well. The fossil that we can see is most probably of a carnivorous dinosaur or a very large carnivorous reptilian.
False. Contour lines indicate different levels of elevation. One line might indicate an elevation of 100 feet, and the line next to it an elevation of 200 feet, and so on. When those lines are close together it means that the elevation is rising very quickly from 100 feet to 200 feet, which means a steeper slope. When those lines are farther apart, it means that there's a lot more space between the 100-foot elevation and the 200-foot elevation, which means a more gentle slope.
