We know that perimeter of the figure=perimeter of semi circle+perimeter of rectangle so perimeter of semicircle=2*pi*r/2----> pi*r diameter=6 yd radius r=6/2----> r=3 yd
convert to ft 1 yd ------> is equal to 3 ft 3 yd-----> x x=3*3----> x=9 ft so diameter=18 ft radius=9 ft perimeter of semicircle=pi*9----> 28.26 ft
perimeter of rectangle=18+15+15----> 48 ft
perimeter of the figure=28.26 ft+48 ft-----> 76.26 ft
