You have to use Pythagorean's theorem to find the missing side measure. 41^2=40^2 + w^2. 1681 = 1600 + w^2. 1681-1600=w^2. 81=w^2 and w = 9. That's an odd triangle, but accurate! Now use the cos definition of cos x = 9/41, and cos x = .2195. Now use the inverse function on your calculator in degree mode to see that the angle x is 77.3 degrees.

A/B : 4/9 = 12/B
cross multiply
(4)(B) = (9)(12)
4B = 108
B = 108/4
B = 27
P = 4a...where a is the length of one side
P = 4(27)
P = 108 yds <=== perimeter of square B
