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!
