Answer:

Base = 8 * 17

Explanation:

(Not sure what the "8" is, assuming an accidental input.)

Base area = 3536/26 = 136

136 = Lw

L = 136/w

L = w + 9

136/w = w + 9

136 = w(w + 9)

136 = w² + 9w

w² + 9w - 136

(w + 17)(w - 8)

Only use the positive result. w = 8

L = 8 + 9 = 17

Edit: Maybe 8 is the answer accidentally included in the question?...
