Formulas for finding area of different shapes

Real life applications of Area.

My Summary No.1


Area
Area is the amount of two-dimensional space is taken up by any object placed.

The term is only used for 2-D shapes. For calculating the area for different shapes, you need to substitute the values given and solve it.


Formulas for finding area of different shapes
The formulas used for finding area for few shapes are
Square
S2
Rectangle
Length x Breadth
Triangle
1/2x base x height
Parallelogram
Base x Vertical height
Trapezoid
(b1+b2) x h
2

Model Questions & answers
Solution
Area= L X B
Length = 3cm
Breadth= 2cm
A = 3cm X 2cm
A= 6cm2

Solution
Area= b X h
Base= 15in
Height= 8in
15in X 8in
120in
My Summary
Area
Area is the amount of two-dimensional space taken by any object placed. This term is only used for two-dimensional shapes.
For calculating the area for different two-dimensional shapes, you have certain formulas for each shape.
You need to use these formulas by substituting the values given to you to get the area of the shape.
Sometimes, these shapes can be compound too and the question will ask you to find the area but that is only to confuse you and to make the question complex.
Compound shapes are those shapes which consist of more than one shape but to find the area you just need to take the individual shapes and use the formulas to find the area of the shape.

The formulae used for finding area for few shapes are
Square

Rectangle
Length x Breadth
Triangle
1/2x base x height
Parallelogram
