In Class 8, you can calculate the area of a polygon by using one of several formulas based on its shape. For example, the formula for finding the area of a triangle is A = 1/2bh (where b is base length and h is height). The formula for finding the area of a square is A = ...
Step 3– As soon as we select the “ number of sides and outer a “ from the drop-down options, we will notice two boxes where we need to enter these values. Let us take an example. Suppose we wish to find the area of a polygon having 8 sides where each side is of the length ...
Area of a Pentagon is the region enclosed by its five sides. A pentagon can be divided into five equal isosceles triangles to find the area of pentagon formula. Find area using apothem and sides of pentagon.
Area of a Regular Polygon Example 1 Find the area of the equilateral triangle below. Give your answer to 2 decimal places. The equilateral triangle has a side length of 8 cm. The area of an equilateral triangle is: \[ A = { \sqrt 3 \over 4} s^2 \] where s is the length of ...
A polygon is any flat shape that has straight lines for sides. Some common polygons are squares, parallelograms, triangles and rectangles. The area of an object is the amount of square units that are needed to fill a shape. To find the area of a shape, y
Where “a” is the length of the octagon sides. It is not possible to find the area of an irregular octagon using this formula. So, to find its area, it is divided into other regular polygons. Then, the areas of all polygons should be added to get its area. ...

How To Find The Area of a Rectangle Using Area of Rectangle Formula.The area of a polygon is the number of square units inside the polygon. To understand the difference between perimeter and area, think of perimeter as the length of fence needed to enclose the yard, whereas area is the ...
A triangle is a polygon that is made of three edges and three vertices. The vertices join together to make three sides of a triangle. The area occupied between these three sides is called thearea of a triangle. In general, thearea of a triangleis defined by $\frac{1}{2}$ x b x ...
