Step-by-step explanation:

Figure 1:-

___________________________________________

Perimeter of figure 1

  • Perimeter of rectangle + Perimeter of semicircle
  • 2( l + b ) + 2πr /2
  • 2 ( 4 + 7) + (2 x 22/7 x 3.5 )/ 2
  • 22 + 11
  • 33 cm

_______________________________________________

Area of figure 1

  • Area of rectangle + Area of semicircle
  • (l x b) + ( πr² /2)
  • (4 x 7) + (22/7 x {3.5}² /2)
  • 28 + 19.25
  • 47.25cm²

==========================================================

Figure 2:-

______________________________________________________

Perimeter of figure 2

  • Perimeter of rectangle + Perimeter of 2(semicircle) {circle}
  • 2( l + b ) + 2πr
  • 2 ( 14 + 35) + 2 x 22/7 x 7
  • 98 + 44
  • 142 cm

__________________________________________________

Area of figure 2

  • Area of rectangle + Area of circle
  • ( l x b ) + πr²
  • (14 x 35) + 22/7 x 7²
  • 490 + 154
  • 644 cm ²
