Question 771173
Let the length of the rectangle to be x and the width to be y.
{{{2x+2y=24}}}
{{{2x/2+2y/2=24/2}}}
{{{x+y=12}}} ... Find the two numbers which will sum up to 12
{{{1+11=12}}}
{{{2+10=12}}}
{{{3+9=12}}}
{{{4+8=12}}}
{{{5+7=12}}}
{{{6+6=12}}}
{{{7+5=12}}}
{{{8+4=12}}}
{{{9+3=12}}}
{{{10+2=12}}}
{{{11+1=12}}}
Therefore, the possible integer lengths, x are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 whereas
the possible integer widths, y are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11.
