Answer: 45cm
Step-by-step explanation:
The spring stretches 1/3 of the weight attached. 1/3 of 15 is 5. However, the spring is already 40cm long so we must add 5 to 40 to find the total length and of the spring.

Perimeter (P) = 2L + 2w
68 = 2L + 2w
68 - 2L = 2w
2(34 - L) = 2(w)
34 - L = w
********************
Area (A) = L * w
240 = L (34 - L)
240 = 34L - L²
L² - 34L + 240 = 0
(L - 10)(L - 24) = 0
L = 10 or L = 24
w = 34 - L = 34 - 10 = 24 or w = 34 - 24 = 10
Answer: width = 10, length = 24 assuming length is bigger than the width
