Question 408156

the length {{{L}}} of a pool is {{{4}}}{{{ times}}} its width{{{W}}} 

{{{L=4W}}}


if the perimeter {{{P}}} of the pool is {{{140 m}}}, find the length  and width of the pool

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

{{{140m=2(4W+W)}}}

{{{140m/2=5W}}}

{{{70m=5W}}}

{{{70m/5=W}}}

{{{14m=W}}}.....the width


{{{L=4W}}}
{{{L=4*14m}}}
{{{L=56m}}}.........the length
