Hi !
Judy built a rectangular patio that is 9 meters wide and has a perimeter of 40 meters what is the length of Judy’s patio ?
[tex]l=9\;m\\L=x[/tex]
[tex]So\;Perimeter=2(9+x)=18+2x=40\;m\\\\18+2x=40\\2x=40-18\\2x=22\\\\x=\dfrac{22}{2}\\\\\boxed{x=L=11}[/tex]
The lenght of Judy's Patio is 11 meters.
