Find the perimeter of the following figure.
Open in App
Solution
The perimeter of a closed planar figure is the total length of its boundary.
Hence, the perimeter of the given figure
= 4 m + 4 m + 5 m + 4 m + 3 m + 12 m + 3 m + 5 m + 5 m + 5 m + 4 m + 12 m
(Starting from the left topmost edge and going clockwise)
= 66 m
Therefore, perimeter of the given figure is 66 m.
Hence, the perimeter of the given figure
= 4 m + 4 m + 5 m + 4 m + 3 m + 12 m + 3 m + 5 m + 5 m + 5 m + 4 m + 12 m
(Starting from the left topmost edge and going clockwise)
= 66 m
Therefore, perimeter of the given figure is 66 m.
