To find the area of an equilateral triangle, you can use the formula:

Area = (sqrt(3) / 4) * s^2

Where "s" represents the length of one side of the equilateral triangle.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A pyramid has a base in the shape of a rhombus and a peak directly above the base's center. The pyramid's height is #7 #, its base's sides have lengths of #1 #, and its base has a corner with an angle of #(5 pi)/8 #. What is the pyramid's surface area?
- A solid consists of a cone on top of a cylinder with a radius equal to that of the cone. The height of the cone is #36 # and the height of the cylinder is #5 #. If the volume of the solid is #48 pi#, what is the area of the base of the cylinder?
- The base of a triangular pyramid is a triangle with corners at #(2 ,5 )#, #(6 ,3 )#, and #(7 ,8 )#. If the pyramid has a height of #15 #, what is the pyramid's volume?
- What is the area of the equilateral triangle whose side length is a?
- A pyramid has a base in the shape of a rhombus and a peak directly above the base's center. The pyramid's height is #9 #, its base's sides have lengths of #5 #, and its base has a corner with an angle of #(5 pi)/8 #. What is the pyramid's surface area?
