Answer 1

let's draw a line joining A to C

now find the value of AC

From HERON'S FORMULA (h²=p²+b²)

h=

.

.

SQUARE ROOT OF 169=13

AC =Diameter

then radius =AC/2

Radius=13/2=6.5

Area of Circle=

.

=22/7×6.5×6.5

=132.67

Area of Shaded part = Area of Circle-Area of rectangle

=132.67 - 12×5

=132.67 - 60

=72.67

AREA OF SHADED PART= 72.67 APPROX
