The shaded figure comprises 2 radii, 1 curve surface which is equal to 3/4 (270 degrees) of circle circumference because the intersected curved defining the shaded area is symmetrical to intersected curved part of the circle with centre G.

Total perimeter = 3/4 (2 pi r) + 2r = ( 3/4 × 2 x 22/7 × 14) + 2×14

= 66 + 28

**= 94 cm2**

2. Area of the right angle triangle in the middle = Area of the 2 smaller right angles at the side.

= 1/2 (8)(6)=24cm

So area of rectangle = 2x 24= 48 cm2

Side KL = 48/10 =4.8cm

**Ans : (2)**
