It's a rectangle with length 20m and breadth 14m and Two semi circles with radius 7cm.

Total perimeter = Perimeter of rectangle + Perimeter of Circle - 2 times the breadth of rectangle

*We subtract the breadth because it's not the part of perimeter.

= 2*(l+b) + 2*(pi)*R - 2b

= 2*(20+14) + 2*(22/7)*7 - 2*14

= 68 + 44 - 28

= 84m

Similarly for Area

Area = Area of rectangle + Area of circle

= l*b + (pi)*R²

= 20*14 + (22/7)*7*7

= 280 + 154

= 434m²

Hope this helps!
