Step 1
Given: diameter(D) of semi circle =7m, length(l) of rectangle =15m
in one round total distance(d) covered is given by
d=π(D)+2(1)
Step 2
so, distance covered in seven rounds will be
d=7(πD+2(1)) ( π=227, D=7, 1=15)
=7πD+141
=7(227)(7)+14(15)
=154+210
=364m
hence, total distance covered is equal to 364m
