Answer:
What is Area of 2D Shapes?
of any 2D shape is the size of the region enclosed within it. 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 .
area of 2d shapes
The unit of area is called . 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
square
Area of a Square = Side × Side
Area = S × S
square-example
Area = 4 × 4 = 16 sq. cm
Rectangle
rectangle
Area of a Rectangle = Length × Width
= l × w
rectangle example
Area = 8 × 3 = 24 sq. cm
Area of a triangle:
could be of various types, like the equilateral triangle, isosceles triangle, and right-angled triangle but the formula for the area of all kinds of triangles is the same.
area of triangle
We find the area of a triangle using the formula 1⁄2 × b × h, where base (b) is the length of any one side of the triangle and height (h) is the perpendicular distance between the base and the top vertex of the triangle.
Example:
area of triangle example
In the triangle ABC, the base measures 6 units and the height measures 4 units.
So, the area of triangle ABC = 1⁄2 × b × h
= 1⁄2 × 6 × 4
=12 sq units
Circle:
We calculate the area of a by the formula π × r2 , where r is the radius of the circle and π is a constant whose value is 227 or 3.14
circle
Example: Area of the above circle = π × r2
= 3.14 × 42
= 3.14 × 16
= 50.24 sq. cm
Rhombus:
rhombus
The formula to find the area of a is pq/2 where p and q are the two diagonals of the rhombus.
In the rhombus ABCD, we can calculate the area as follows:
Area of rhombus = 1⁄2 pq
= 1⁄2 × 3 × 5
= 7.5 sq cm
Parallelogram:
To find the area of a parallelogram, we use the formula b × h, where b stands for base and h represnts height. The height is the vertical distance between the base and the top.
Example:
parallelogram
In the above figure, the area of the parallelogram is b × h. Therefore it is 6 × 4 = 24 sq. cm
