# P in the Following Figure, Abcd is a Rectangle, Having Ab = 20 Cm and Bc = 14 Cm. Two Sectors of 180° Have Been Cut Off. Calculate: the Length of the Boundary of the Shaded Region. - Mathematics

Sum

In the following figure, ABCD is a rectangle, having AB = 20 cm and BC = 14 cm. Two sectors of 180° have been cut off. Calculate:

the  length of the boundary of the shaded region.

#### Solution

Now we will find length of the boundary of the shaded region.

∴ "Length of the boundary the shaded region"=2pi r+AB+DC

∴ "Length of the boundary the shaded region"=2xx22/7xx7+20+20

∴ "Length of the boundary the shaded region"=2xx22+40

∴ "Length of the boundary the shaded region"=44+40

∴ "Length of the boundary the shaded region"=84

Therefore, length of the boundary of the shaded region is 84 cm
