Answer:ty
Step-by-step explanation:
Answer: 11 ft × 6 ft
Step-by-step explanation: l = w+5. Substitute that value in A = lw and rewrite the equation.
w(w + 5) = 66
w^2 + 5w - 66 = 0 Factor that.
(w -6)(w + 11) =0. Solve for w.
w -6= 0, w = 6 but discard the other -11 as dimensions of real polygons can't be negative
L = w + 5 so L = 6+5
So L=11
