Question 737470

A rectangular field is {{{50m}}} long and {{{30m}}} wide, and if a boy runs it two times cover a distance of two times perimeter of the field

so, {{{2P=2(2L+2W)}}}

{{{2P=2(2*50m+2*30m)}}}

{{{2P=2(100m+60m)}}}

{{{2P=2(160m)}}}

{{{2P=320m}}}...boy will cover a distance of {{{320m}}}
