Question 318557
{{{L-27=W}}} because if the length is decreased by 27 on both sides then all sides would be equal making a square
{{{P=2(L+W)}}}
P=294
{{{294=2(L+(L-27))}}} add like terms
{{{294=2(2L-27)}}} distribute the 2
{{{294=4L-54)}}} add 54
{{{348=4L}}} divide by 4
{{{62=L}}}
{{{L-27=W}}}
{{{62-27=W}}}
{{{35=W}}}
