apply Pythagoras in triangle abc where AC is equals to 13 cm and AB is equal to 12 cm
this implies BC is equal to 5 cm
now quadrilateral ABCD is a rectangle
find the area of rectangle ABCD which comes out to be 12x5=60 square cm................(eq.1)
now find the area of circle
A=πr2 (this 2 is square of r)
now, area of circle is 176.71square cm................(eq. 2)now subtract equation 1 and 2
we get the answer to be =116.71 square cm
