(Help pls! Fast! )1-Williams Garden has a perimeter of 14 M the length is 5 m what is the width of his garden (we want to find the the width since we are giving the perimeter we know with equals (perimeter - length - length)÷2)

2-if William wants to put a fence with two rails around his garden what length of rails should he buy (using the perimeter above we need to multiply perimeter X number of rails)
Thanks!
