How do you find the area of a plane figure?
Area of Plane Shapes
- Triangle. Area = ½ × b × h. b = base. h = vertical height.
- Square. Area = a2 a = length of side.
- Rectangle. Area = w × h. w = width.
- Parallelogram. Area = b × h. b = base.
- Trapezoid (US) Trapezium (UK) Area = ½(a+b) × h.
- Circle. Area = π × r2 r = radius.
- Ellipse. Area = πab.
- Sector. Area = ½ × r2 × θ r = radius.

What is area of combination 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, and 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 plane shapes with examples?
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.
How many planes are in a figure?
A plane figure is a geometric figure that has no thickness. It lies entirely in one plane.
What is the area of each shape?
The area of a shape is the “space enclosed within the perimeter or the boundary” of the given shape.
What are primary 4 plane shapes?
The basic plane shapes are triangle, square, rectangle, oval, circle, and polygons.
What is the total area of the figure?
The area of a figure is counted as the number of unit squars required to cover the overall surface area of that particular 2-D shape. Square cms, square feet, square inches, square meters, etc., are some of the common units of area measurement.

How do you solve a plane shape?
AREA OF PLANE SHAPES
- The area of a shape is a measure of its surface.
- Area is measured in units such as cm² or m², which are derived from the SI units of length.
- The areas of common plane shapes are as follows: Rectangle = L × B. Square = L² Parallelogram = Base × Height. Triangle = ½ × Base × Height.

Definition of plane figure
: a geometrical configuration all of whose points lie in a plane.
What is the area of any triangle?
The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h.
