The area of the wings is given as 140 square feet, and the length (L) is 31 feet longer than the width (W). This can be set up as two equations: L = W + 31 and L*W = 140. Substituting the first equation into the second gives W(W + 31) = 140. Solving this quadratic equation, we find that W = 4 and L = 35, making the dimensions 4 ft × 35 ft.
