Question 713863
Perimeter = 96
let x represent the width.  Then the length is represented by x+8
The equation to solve then would be 2(x+x+8)=96 which simplifies to 4x+16=96
Isolating the variable leaves 4x=80, or x=20
The length is 20m and the width is 28m.  Checking...
2x20=40 + 2x28=56.  40+56=96
