How do you measure area of irregular shape of an object?

Measurement of Area of Irregular Shape: The area of an irregular object can be obtained by drawing an outline of the shape of the object on a graph paper of 1 square centimeter marked square. The number of complete squares is counted. Next squares more than half are also counted as a complete square.

What is a irregular polygon?

An irregular polygon is a 2D shape that has straight sides that are not equal to each other and angles that are not equal to each other. You need to be able to classify geometric shapes based on their properties and sizes and find unknown angles in any polygon.

How do you find the area of land with 4 unequal sides?

Area = (Side 1 × Side 2) × sin (angle) or A = (s1 × s2) × sin(θ) (where θ is the angle between sides 1 and 2). Example: You have a kite with two sides of length 6 feet and two sides of length 4 feet. The angle between them is about 120 degrees.

How do you find the area of an irregular shape with 6 sides?

Irregular Hexagon: Area

  1. Step One: Organize the Hexagon into Triangles and Rectangles. There’s no specific formula for finding the area of a hexagon.
  2. Step Two: Find the Area of Each Shape. Shape A.
  3. Step Three: Add the Areas of All the Shapes Together. The areas of A + B + C + D = the area of the hexagon.

What is an example of an irregular polygon?

An irregular polygon does not have all its sides equal and not all the angles are equal in measure. Examples of irregular polygons are scalene triangle, right triangle, isosceles triangle, rectangle, parallelogram, irregular pentagon, irregular hexagon, etc.

How do you find the area of 4 unequal sides?

Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.
