From cosine law
c^2 = a^2 + b^2 -2abcos(C)
cos(C) = (a^2 + b^2 - c^2)/2ab
this formula will solve your problem

What’s the question here ????
Length (L): 3w
width (w): w
Perimeter (P) = 2L + 2w
32 = 2(3w) + 2(w)
32 = 6w + 2w
32 = 8w
4 = w
Length (L): 3w = 3(4) = 12
Answer: width = 4 meters, length = 12 meters
