Answer:
Given that,
The irregular shape with its dimension.
To find: the area of the given irregular shape.
Explanation:
To find the area of the irregular shape,
first we need to divide the irregular shape into regular shaps (loke rectangle, square etc..,)
we get,
Area of the irregular shape= Area of 1 + Area of 2 + Area of 3 ------------------------(1)
Since 1 and 2 are in same dimension, we get
Area of 1 = Area of 2
We know that,
Area of the rectangle is,
[tex]l\times b[/tex]where l and b are the length and breadth of the rectangle respectively.
Using this and the equation (1), we get
[tex]=11\times4+11\times4+6\times2[/tex]we get,
[tex]=100cm^2[/tex].
Shade the given irregular shape by pink color.
