Answer:

PLEASE MARK ME AS THE BRAINLIEST

Step-by-step explanation:

(i) Total area = Area of the rectangle + Area of the semicircle

= (l×b) + 1/2 (πr²)

= ( 4 × 3 ) + 1/2 ( π × 16 )

= 12 + 8π

= 12 + 25.12

Area. = 37.12 m². -------------------------------- (1)

(ii) Total Area = (1) + area of semicircle of radius 2 cm

= 37.12 + 1/2 (π r²)

= 37.12 + 1/2 ( π × 4 )

= 37.12 + 2π

= 37.12 + 6.28

Area = 43.4 m²
