Answered by BabesLuvBio

As we have to find the perimeter the diameter of the semicircle is not to be added

Attachments:

shivapriyameethal: Should we subtract 21cm from 43cm?

BabesLuvBio: No why shall we

BabesLuvBio: The perimeter is 43cm

shivapriyameethal: But for the given polygon, perimeter doesn't include 21cm

BabesLuvBio: see in the figure u have put a dotted line that separate the triangle from the semicircle...isn't it

BabesLuvBio: The perimeter means the sum of the boundary of the figure

BabesLuvBio: Hope u understand

shivapriyameethal: ok
