what is the area?
taking the length to be 2x+4 and the width to be x,
[tex]62 = 2(2x + 4 + x)[/tex]
hence,
[tex]6x = 54[/tex]
and thus
[tex]x = 9[/tex]
that means the width is 9.
since we established that the length is (2x+4), we can substitute x=9 into the equation. hence,
[tex]2x + 4 = 2(9) + 4 = 22[/tex]
therefore the length is 22
use the area to check your answer!
