# What is the area of a plane figure?

## What is the area of a plane figure?

Definition of Area: The area (A) of a closed plane figure is the region of the plane enclosed by the figure’s boundary. Area is measured in square units of length such as square centimetre (cm2) and square metre (m2).

What are the 10 plane figures?

The different types of plane figures are given below:

• Square.
• Rectangle.
• Triangle.
• Circle.
• Pentagon.
• Octagon.

What are the 5 plane figures?

There are many kinds of plane shapes, but we will focus on 5 basic kinds: squares, rectangles, circles, triangles, and octagons.

### How many types of plane figures are there?

Examples of plane shapes are triangles, quadrilaterals, circle and other polygons. Types of triangles: Isosceles triangle: This is a triangle in which two sides are equal in length and have two equal base angles.

What is areas of combinations of plane figures?

Area of circle = π × r2 Square units, where r is the radius of a circle. Area of parallelogram = b × h Square units, where b is the base, h is the vertical height of the parallelogram. Area of Trapezium = ½(a+b) × h Square units, where a and b are the length of the parallel sides and h is the height.

What are the properties of plane figures?

A plane shape is a two-dimensional closed figure that has no thickness. A plane in geometry is a flat surface that extends into infinity in all directions. It has infinite width and length, zero thickness, and zero curvature.

## What are the properties of all plane shapes?

What is plane figure and types?

A plane figure is a geometric figure that has no thickness. It lies entirely in one plane. Below are examples of different types of plane figures. A plane figure can be composed of line segments, curves, or a combination of the two. Plane figures are often categorized as open or closed.

How do you find area of a figure?

How to calculate area?

1. Square area formula: A = a²
2. Rectangle area formula: A = a * b.
3. Triangle area formulas: A = b * h / 2 or.
4. Circle area formula: A = πr²
5. Circle sector area formula: A = r² * angle / 2.
6. Ellipse area formula: A = a * b * π
7. Trapezoid area formula: A = (a + b) * h / 2.
8. Parallelogram area formulas:

### What are plane shapes called?

Plane shapes are two-dimensional and have only breadth and width. Examples of plane shapes are squares, rectangles, circles, triangles and ovals. They are also called flat shapes or plane geometric figures.

What are the properties of plane shapes?

A closed, two-dimensional or flat figure is called a plane shape. A plane shape has length and breadth, but no thickness. You have learnt about squares, rectangles, trapeziums, triangles and circles in previous years. These are examples of plane shapes.

What are plane figures in basic technology?

INTRODUCTION: A plane shape is a geometrical form such that the straight line that joins any two points on it wholly lies on the surface. Examples of plane shapes are triangles, quadrilaterals, circle and other polygons.
