Answer:
Step-by-step explanation:
w = w
L = 9*w - 29
Area = L*w
area = 9418
w * (9w - 29) = 9418
9w^2 - 29w - 9418 = 0 This monster factors, believe it or not
(9w + 277)(w - 34) = 0
9w + 277 =0
9w = - 277
w = -30.777778
w - 34 = 0
w = 34
The length = 9w - 29
L = 9*34 - 29
L = 306 - 29
L = 277
Check
Area = L * w
Area = 277 * 34
Area = 9418 just as it should.
