To find :area of he arrow...
To construct: join point C to point D
Solution: in triangle ABE
We have, BE=6inches
Height =AL=8-5=3
Therefore ,Area of triangleABE=1/2*b*h=1/2*6*3=9 inch sq
Now ,CDGF is a rectangle
=>area of a rectangle=l*b=5*4=20inch sq
Now area of the given arrow=area of triangle +area of rectangle=9+20=29inch sq
Therefore option(2.)is the answer to ur question....
Hope this helps u...!!!!

Answer:

18.7939 m

Step-by-step explanation:

-Let x be the distance between John and clock tower.

-Let y be the vertical distance from the eyes of the two men standing to the top of the clock tower.

#Taking the right triangle ACD:

$\Tan \ theta=\frac{Perpendicular \ Height}{Base}\\\\Tan \ 60\textdegree=\frac{y+1.5}{x}\\\\y=x \ Tan \ 60\textdegree -1.5$

#Taking the right triangle ABD:

$\Tan \ theta=\frac{Perpendicular \ Height}{Base}\\\\Tan \ 40\textdegree=\frac{y+1.5}{x+20}\\\\y=(x+20)\ Tan \ 40\textdegree -1.5$

#We equate the two yo solve for x and y;

$(x+20)\ Tan \ 40\textdegree -1.5=x\ Tan \ 60\textdegree -1.5\\\\(x+20)\ Tan \ 40\textdegree=x\ Tan \ 60\textdegree\\\\0.8391x+16.7820=1.7321x\\\\x=18.7939$
