Question 1178017


if the length of a rectangle is six times the width, we have

{{{L=6W}}}......eq.1

If the area of the rectangle is {{{294}}} square inches, we have



{{{L*W=294}}} ...........substitute {{{L}}}

{{{6W*W=294}}}

{{{W^2=294/6}}}

{{{W^2=49}}}

{{{W=7}}}

then

{{{L=6W}}}=>{{{L=6*7}}}=>{{{L=42}}}
