Find the area of the pentagon. Problem 4 :. Problem 5 :. Problem 6 :. The enclosure on the floor underneath the Foucault Pendulum at the Houston Museum of Natural Sciences in Houston, Texas, is a regular dodecagon with a side length of about 4.
What is the floor area of the enclosure? To find area of any regular polygon, we need to know the length of apothem and perimeter. Solution :. To apply formula for the area of a regular pentagon, we must find its apothem and perimeter. The area of the pentagon is. To apply formula for the area of a regular hexagon, we must be knowing the apothem and perimeter.
Apothem is already given and we have to find the side length ED of the polygon to find its perimeter. Subtract from each side. Take square root on each side. So, the hexagon has the perimeter of.
The area of the hexagon is.Geometry area apothem worksheet keyword after analyzing the system lists the list of keywords related and the list of websites with related content, in addition you can see which keywords most interested customers on the this website.

The area of a rectangle is equal to the product of the length of its base and the length of its height. Sometimes, the height is called the "altitude". We can also call the longer side the "length" and the shorter side the "width".
Worksheet 1Worksheet 2Worksheet 3 to calculate the area and perimeter of rectangles. Area of a Parallelogram. To get the area of a parallelogramwe first draw a perpendicular line segment from one corner of the parallelogram to the opposite side. This is the height h of the parallelogram. The area of a parallelogram is equal to the product of its length and height.
Remember to always use the perpendicular height. You may notice that lh is also the area of a rectangle with dimensions l and h. The diagram below will explain why.
If we cut out the triangle ABC and add it to the other side triangle DEFyou will have a rectangle with dimensions l and h that has the same area as the original parallelogram. Worksheet to calculate the area of parallelograms. To get the area of a trianglewe first choose one of the sides to be the base b. Then we draw a perpendicular line segment from a vertex of the triangle to the base. This is the height h of the triangle. The area of a triangle is equal to half the product of the base and the height.
There are also other formulas for the area of a triangle. More examples, formulas and videos for area of triangles. If the lengths of the diagonals are a and bthen area of the rhombus is equal to half the product of the diagonals. If you are given the length of one side s and the perpendicular height h from one side to the vertex then the area of the rhombus is equal to the product of the side and height. This formula for the area of a rhombus is similar to the area formula for a parallelogram.
Area of a Kite The area of a kite uses the same formula as the area of a rhombus. The area of a kite is equal to half the product of the diagonals. To get the area of a trapezoidwe sum the length of the parallel sides and multiply that with half of the height. Remember that the height needs to be perpendicular to the parallel sides. Worksheet to calculate area of polygons.
A regular polygon is a polygon where all the sides are the same length and all the angles are equal. The apothem of a regular polygon is a line segment from the center of the polygon to the midpoint of one of its sides. The area of any regular polygon is equal to half of the product of the perimeter and the apothem.
