I have received another answer: answer is area=(cot(pi/5))^2/2 I think the correct answer is greater than 1. The answer above is less than 1.

Find the area of the largest square that can fit inside a regular pentagon of unit side length.

Anyone has got a copy? Please

(a) 4.35/.8 = 5.44 years (b) Proper time = 5.44 x (1 - 0.8^2)^0.5 = 3.26 years (c) Contracted length = 4.35c x (1 - 0.8^2)^0.5 = 2.61c metres

I was not referring to that at all.

Can you spot the problem with the solution method in Q1d? The answer is correct. I wonder why nobody queries that.
