anonymous · Answer

so the key words here are square and semicircle

give me equations for the area of a square and a circle

anonymous · Answer

area of square part of arch is 10*10=100
now...the diameter of the circle is 10
therefor radius is 5 and area is $$\pi*r^2=\pi*25$$

therefore total area is 100+25pi

incorrect @tanmaykhandait

y?

anonymous · Answer

since it is a square both sides are the same

Asquare=L*L=10*10=100

Acircle=pi*r^2

Asemicircle=Acircle/2

the radius of the semicircle is half the distance of the L of the square

so you get 

Atotal:100+25*pi/2
