Step-by-step explanation:
Answer to apx
Length (L): L
width (w): 1/2L + 3
Area (A) = L x w
308 = (L)(1/2L + 3)
308 = (1/2)L² + 3L
616 = L² + 6L
0 = L² + 6L - 616
0 = (L - 22)(L + 28)
0 = (L - 22) 0 = (L + 28)
L = 22 L = -28
Since length cannot be negative, disregard the -28
L = 22
width (w): 1/2L + 3 = 1/2(22) + 3 = 11 + 3 = 14
Answer: width = 14 meters, length = 22 meters
