What are the names of irregular shapes?
Any polygon that does not have all congruent sides is an irregular polygon.
Irregular polygons can still be pentagons, hexagons and nonagons, but they do not have congruent angles or equal sides.
Here are some examples of irregular polygons..
How do you calculate area of a shape?
Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn’t on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale).
How do I calculate the area of an irregular shape?
To find the area of irregular shapes, the first thing to do is to divide the irregular shape into regular shapes that you can recognize such as triangles, rectangles, circles, squares and so forth… Then, find the area of these individual shapes and add them up!

What does it mean to find the area of a shape?
In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc.
What’s the formula for calculating the area of a circle?
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
What is area and perimeter?
About Transcript. Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.
How do you find the area of an irregular shape with 4 sides?
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.
