The formula for finding the perimeter of a regular polygon is just the number of sides x the length of any side. Once you've multiplied those 2 numbers together, you've found the perimeter of the polygon!

At least, how do you find out 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.

So too, how do u find the perimeter of a shape? The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.

Yet, what is the perimeter of a regular polygon?

The perimeter of a regular polygon = (length of one side) × number of sides. Perimeter of a regular hexagon = 4 cm × 6. = 24 cm. Example 2: A pentagon has all sides equal to 6 cm.

How many sides are there in Polygon?

Triangle - 3 SidesSquare - 4 Sides
Pentagon - 5 SidesHexagon - 6 sides
Heptagon - 7 SidesOctagon - 8 Sides
Nonagon - 9 SidesDecagon - 10 Sides

### What is the Apothem of a polygon?

The apothem (sometimes abbreviated as apo) of a regular polygon is a line segment from the center to the midpoint of one of its sides. Equivalently, it is the line drawn from the center of the polygon that is perpendicular to one of its sides. The word "apothem" can also refer to the length of that line segment.

### What is the area of a polygon with 4 sides?

2)/2 or A = (d1 × d2)/2. Example: A four-sided shape has two adjacent sides with lengths of 4 meters. You can find the area of this square by multiplying its base times its height: 4 × 4 = 16 square meters. Example: A square's diagonals are both equal to 10 centimeters.

### What is a perimeter in math?

Perimeter is the distance around the edge of a shape. Learn how to find the perimeter by adding up the side lengths of various shapes.

### How do you find the perimeter given the area?

Perimeter of a Rectangle
• Remember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)
• Substitute the known values into the area formula. 36 = 4 * w. ...
• Substitute values for length and width into the perimeter formula.
• ### What is the difference between area and perimeter?

Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.

hectogon

pentagon

dodecagon

### What is the formula for regular polygon?

You also learned the formula for finding the area of any regular polygon if you know the length of one side and the apothem: A = (n × s × a)2 A = ( n × s × a ) 2 , where n is the number of sides, s is the length of one side, and a is the apothem.

### How do you find the area of an irregular polygon?

To find the area of an irregular polygon you must first separate the shape into regular polygons, or plane shapes. You then use the regular polygon area formulas to find the area of each of those polygons. The last step is to add all those areas together to get the total area of the irregular polygon.

### Is the Apothem equal to the side?

When a hexagon is regular it has six equal side lengths and an apothem. An apothem is a line segment from the center of a polygon to the middle point of any one side. ... As long as you know the side length of the hexagon, you can calculate the length of the apothem.

### How do you find the Apothem of a polygon without area?

We can also use the area formula to find the apothem if we know both the area and perimeter of a polygon. This is because we can solve for a in the formula, A = (1/2)aP, by multiplying both sides by 2 and dividing by P to get 2A / P = a. Here, the apothem has a length of 4.817 units. to find the length of the apothem.
