Answer:
L= 4 + W
Area is 45, so
L times W = 45
substituting the value of L, we get (4+W)*W=45, after simplifying this we get
4W+W2=45
W2+4W-45=0, this is a quadratic equation and after solving this we get the factors 9 and -5
( W+9) and (W-5) = 0
after solving for W we get W=-9 or W=5, since width cannot be negative, so width = 5
Now substituting the value of W=5 in L = 4 +5, we get length = 9
