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.

The area is measurement of the surface of a shape. To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y.

Multiply the length of one side of a regular polygon by the number of sides to find its perimeter. Regular polygons have identically sized sides. For example, if the shape is a regular pentagon, which has 5 sides, with a side length of 4 inches, then multiplying 4 inches by 5 results in a perimeter of 20 inches.

Since a square has sides that are all the same length, the formula just requires us to square the length of one side, which is the same as multiplying the width and the height. Area = length of one side = 6 cm = (6 cm)2 = 6 cm x 6 cm = 36 cm2.

Find the base's area with the given shape's area formula, then multiply the area by 2. In this example, the formula for the base's area is width multiplied by length, or 4 multiplied by 6, which equals 24 square inches, and 24 multiplied by 2 results in 48 square inches.

Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

Area is measured in square units. The area of the rectangle can be calculated using the following formula: A = l   w, where l represents the length and w represents the width. Perimeter is the length of the boundary of the shape. It can be calculated adding the measurements of each side.

The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°.

The sum of all of the interior angles can be found using the formula S = (n - 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.

Finding the Perimeter of a Polygon The distance around a polygon is called the perimeter. To find the perimeter of any polygon you add the lengths of its sides. For example the perimeter of the irregular polygon below is 12 units.

A trapezoid will have two sides parallel. Add the lengths of these parallel side, find its average and multiply this average length by the distance between these lines and you get the area.

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.
