For this case we have that the area is given by:
 A = (w) * (l)
 Where,
 w: width
 l: long
 Substituting we have:
 66 = (w) * (w + 5)
 Rewriting
 w ^ 2 + 5w - 66 = 0
 (w + 11) * (w-6) = 0
 Using the positive root we have:
 w = 6
 Answer:
 
the width of the frame is:
 
w = 6 cm

Answer:

x=-1,-2

Step-by-step explanation:

Multiply the given equation with (x+1) on both sides. We'll get,

x+2/x=-3

or,x^2+2=-3x

or,x^2+3x+2=0

or,x^2+2x+x+2=0

or,x(x+2)+1(x+2)=0

or,(x+2)(x+1)=0

or,x=-2,-1
