Answer:
E
Step-by-step explanation:
i guess the dotted lines outline a square
so get the area of the square which is 6×6=36
then don't focus on the shaded part but unshaded you'll see two right angled triangles

you will get a total for both as 21
then get the area of the square 36-21=15
so the area becomes 15
Well u add your problem and get your answer
H^2=x^2+y^2
y^2=h^2-x^2
y^2=40^2-24^2
y^2=1024
y=√1024
y=32 ft
