How do you find the area of 2D shapes?
Area of any 2D shape is the size of the region enclosed within it….Area Of 2 D Shapes – Definition with Examples.
| 2D Shape | Area Formula | Example |
|---|---|---|
| Square | Area of a Square = Side × Side Area = S × S | Area = 4 × 4 = 16 sq. cm |
| Rectangle | Area of a Rectangle = Length × Width = l × w | Area = 8 × 3 = 24 sq. cm |
How do you find the area and perimeter of a 2D shape?
The perimeter of a shape is the distance all the way around the sides of the shape. The area of a shape is the flat space inside the shape….The following are important formulae to remember:
- d=2πr and r=12d.
- Circumference of a circle (c)=2πr.
- Area of a circle (A)=πr2.
What is the formula for area of a shape?

What units do you use for area?
In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares.
What units are used for areas?
Area – The common metric measurements for area are square centimeter, square meter and hectare (10,000 square meters). Areas of glass panes are measured in square centimeters. Building and floor areas are measured in square meters. Farm land is expressed in hectares.
How to calculate the area of a 2D shape?
Different shapes have a different formula for calculating the area. Area of a square and a rectangle: The area of a square and a rectangle is the product of its two adjacent sides. 2D Shape. Area Formula. Example. Square. Area of a Square = Side × Side. Area = S × S.
What are the different types of 2D shapes?
There are several 2D shapes such as square, rectangle, circle, rhombus, and triangle. The colored region in each shape represents the area of the respective shape. The unit of area is called square units.
Which is the standard unit of area for a shape?
According to the International System of Units (SI), the standard unit of area is the square meter (written as m 2) and is the area of a square whose sides are one meter long. For example, a particular shape with an area of three square meters would have the same area as three such squares.
Which is an example of an area of a shape?
An area is a quantity that expresses the extent of a two-dimensional figure or shape or planar lamina in the plane. Lamina shapes include 2D figures that can be drawn on a plane, e.g., circle, square, triangle, rectangle, trapezium, rhombus and parallelogram. Polygon shape: A polygon is a two-dimensional shape that is formed by straight lines.
