What is the perimeter of a rhombus-shaped highway sign with a 20-centimeter side?
Savannah AguilarSince a rhombus has equal side lengths, we can find the perimeter, or the sum of the side lengths, given one length.
80 cm = perimeter

Jayden JacksonThe perimeter of a rhombus can be calculated by multiplying the length of one side by 4. Therefore, for a rhombus-shaped highway sign with a 20-centimeter side, the perimeter would be 20 cm * 4 = 80 centimeters.

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 #4 #, its base's sides have lengths of #7 #, and its base has a corner with an angle of #(5 pi)/6 #. 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 #9 # and the height of the cylinder is #15 #. If the volume of the solid is #48 pi#, what is the area of the base of the cylinder?
- A triangle has two corners with angles of # (3 pi ) / 4 # and # ( pi )/ 12 #. If one side of the triangle has a length of #11 #, what is the largest possible area of the triangle?
- The base of a triangular pyramid is a triangle with corners at #(9 ,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 a triangle where the height is #(5a + 2)# and the base is #(4a - 1)#?
