Solution
For calculating the perimeter of the given coloured shape.
We have to find the total length of the boundary of the given shape.
The length of each side of square grid is 1 cm so we just need to count the number of squares along the boundary of the given shape.
There are 20 square edges along the boundary of the shape.
Perimeter of the given coloured portion = 20 cm.
