Answer:
239.92
Step-by-step explanation:
53.94×4=215.92
Then you do 21×2=24 then you take the 215.92 and the 24 and add them together and it gives you 239.92
You have to get p by itself so add 18 to Both sides and -18 + 18 is 0 and 18+3 is 21 so p=21
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...
