Find Area of Irregular Shapes Example

From the above Image
Area of the Triangle:
Height = 4
Base = 4
Area of the Triangle = Ĺ(BxH)
= 4x4/2
= 8
Area of Rectangle 1:
Length = 12
Breadth = 4
Area of Rectangle = LxB
= 12x4
= 48

Area of Rectangle 2:
Length = 4+6+5 = 15
Breadth = 6
Area of Rectangle = LxB
= 15x6
= 90.

Area of Rectangle 3:
Length = 5
Breadth = 4
Area of Rectangle = LxB
= 5x4
= 20.

Area of the given figure = Area of Triangle + Area of Rectangle 1 + Area of Rectangle 2 + Area of Rectangle 3
= 8 + 48 + 90 + 20
= 166
Hence the required Area of the given figure is 166.
The above worksheet is an walk through to understand the concept of Calculating Area of Irregular Shapes. When it comes to online calculation this Area Volume Calculator to find area of each area.
