Answer 1

area of equilateral triangle=√3×a^2/4=100√3/4=25√3cm^2

we can consider BDF,DCE,and AEF as hexant of circle,centred at B,C and A respectively,with radius as BD=10/2=5

shaded area=total area-unshaded area

unshaded area=area of three hexant of Circle

shaded area=(25√3-3×3.14×25/6)cm^2

=25×3.14-1.57×25

=25×1.57=39.25
