Question 343662
{{{PerimeterOfRectangle = 2*Length + 2*width}}}
{{{78 = 2*(2x+3) + 2*(2x-4)}}}
{{{78 = 4x + 6 + 4x - 8}}}
{{{78 = 8x -2}}}
{{{80 = 8x}}}
{{{10 = x}}}
If x = 10, then
{{{Width = 2*10 -4}}}
{{{Width = 20-4}}}
{{{Width = 16}}}
{{{Length = 2*10 + 3}}}
{{{Length = 20+3}}}
{{{Length = 23}}}
