Here,
In Right angle triangle,
base = 12 m
height = 8 m
Now,
◇ Area = 1/2*b*h
= 1/2*12*8
= 48 m^2
In semicircle,
radius = 4 m
Then,
◇Area" = 1/2*22/7*r^
= 1/2*22/7*4*4
= 25.14m^2
Again,
◆Total Area = Right triangle + semicircle
= (48+25.14) m^2
= 73.14 m^2
This is right answer...
I hope you understand...
Mark me as brainliest...
Thank you ♥♥
For 7, when GH=HI, that means mG=mI so mI is 55
for 8, mJ would equal 58 since 180-122 is 58. 58+67 is 125 and 180 - 125 is 55, so mk is 55
