Question

in the given figure ​

Answer 1

Answer:

abcd is trezium

ad=bc   (property of trapezium)

ab=bc=ad=7      given-----1

bc=ec=7    radii of same circle

from 1

ab=bc=ec=ad=7  ---------2

d-e-c

de+ec=dc

4+7=dc

dc=11

aea of trapezium=(sum of parallel line)*concrent side/2

=(7+11)*7/2

=18*7/2

=63cm^2  ----------2

area of sector=theta /360 pie   * r^2

=60/360  *22*7*7/7

=22*7*/6

=154/6

=77/3

=25.667

area of shaded region+area of sector=area of trapezium

shaded region+25.667=63

x=63-25.667=37.33

area of shaded region=37.33

hope this is helpful
