Question 632289
Let {{{x}}} - the width
Then {{{4x}}} - the length
The perimeter of a rectangular is {{{P=2(w+l)}}}, where {{{w}}} is the width, {{{l}}} is the length of a rectangular
The equation
{{{70=2(x+4x)}}}
{{{2*5x=70}}}
{{{10x=70}}}
{{{x=7}}} meters is the width of  a rectangular
{{{4x=4*7=28}}}meters is the length of  a rectangular
