How to find the area of irregular shapes?
We can find the area of irregular shapes using the unit square method with the following steps:
- Divide the given irregular shape into small squares of the unit square area.
- The total number of unit squares falling within the shape determines the total area.
- While calculating the area for a more accurate estimate count the square as “1” if the shaded region covers more than half of each square.

How do you find the area of a 4 sided polygon?
If the diagonal and the length of the perpendiculars from the vertices are given, then the area of the quadrilateral is calculated as: Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.
How do you find the area of a polygon with n sides?
What is the formula for the area of a regular polygon of n-sides? The formula for the area of a regular polygon of n-sides is [l2n]/[4tan(180/n)] Square units, where l is the side length of the polygon and n is the number of sides.
How do you calculate square feet with 5 sides?

Squares and rectangles are easiest, followed by triangles and then circles.Figure the area of each shape. ... Add the areas of all the individual shapes to find the total square footage.
How do you find the perimeter of a 5 sided shape?
If all the sides of a pentagon are of equal length, it is known as a regular pentagon. In this case, the perimeter of the pentagon can be calculated with the help of the formula, Perimeter = 5 × side length. For example, if one side of a regular pentagon is 8 units, its perimeter will be, P = 5 × 8 = 40 units.
Is a pentagon a polygon?
The pentagon is one of the types of polygons. The sum of all the interior angles for a regular pentagon is 540 degrees.
What is the formula for area of regular polygon?
The area of a regular polygon is one-half the product of its apothem and its perimeter. Often the formula is written like this: Area=1/2(ap), where a denotes the length of an apothem, and p denotes the perimeter.

And Width of the vertical sides into Width 1 and Width 2. ... Step 3: Press calculate button. ... Our Formula: Area = b × h.
How do you find the area of a 8 sided polygon?
If the shape is a polygon and it has eight sides, we call it an octagon. To find the area of an octagon we use the following formula. Area of octagon formula = 2 × s2 × (1+√2). Where "s" denotes the length of the side of an octagon.
What is the formula for Area of a regular polygon?
The area of a regular polygon is one-half the product of its apothem and its perimeter. Often the formula is written like this: Area=1/2(ap), where a denotes the length of an apothem, and p denotes the perimeter.
What is the formula for the perimeter of a polygon?

How to find the area of a polygon?
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
How to find the area of a square?
Find the area of a square. To find the area of a square, just square the length of one side. This is really the same thing as multiplying the base of the square by its height, because the base and height are the same. If the square has a side length of 6, then the area is 6 x 6, or 36.
How to make an array of coordinates?
Create an array. List the x and y coordinates of each vertex of the polygon in counterclockwise order. Repeat the coordinates of the first point at the bottom of the list.
How to add the sum of the vertex products?
Multiply the x coordinate of each vertex by the y coordinate of the next vertex. Add the results. The added sum of these products is 82.
How to find the perimeter of a hexagon?
You know that x = half the length of the bottom side of the triangle. Double it to get the full length. The bottom side of the triangle is 20 units long. There are six of these sides to the hexagon, so multiply 20 x 6 to get 120, the perimeter of the hexagon.
