Answer:
hemisphere perimeter = πr+2r
= 22/7×14+2(14)
= 72cm
rectangle perimeter = 2(l+b)
= 2(14+21)
= 2(35)
= 70cm
total perimeter= 72+70= 142cm
area of hemisphere= πr²/2
= 308cm²
area of rectangle= l×b
= 14×21
= 294 cm²
total area= 308+ 294= 602cm²

Answer:
Perimeter = 2(21 + 14) + 22/7 × 7 + 2 × 7 + 22/7 × 21/2 + 2 × 21/2 = 70 + 34 + 54 = 158 cm
Area = 294 + 77 + 173.25 = 544 sq. cm .
