You are a woodworker who is designing a custom doghouse. The doghouse will have an A frame, with the front and back of the house in the shape of a triangle. The customer has chosen a different siding for the back of the house, and you need to determine the area in order to place the order. The base of the triangle measures 3 feet, 2 inches, and the height is 4 feet. What is the area of the back of the doghouse to the nearest square inch?

step-by-step explanation:

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
