Geometry Questions

WOW!   THAT is an awful lot of questions to have to go trapsing all over the internet to see....

   How about submitting ONE at a time with the information in your question instead of links????

Thanx !  

S**t! He’s too fucking lazy to do that. He’s too fucking lazy to check if anyone answered them, he just reposts them.  

First one:

The Perimeter is  15 x4 = 60 feet

She also wants TWO diagonals of the square room

by the pythagorean theorem for R triangles the diagonal can be found as

 a^2 + b^2 = c^2       Where a  and b  are sides of the triangle and c is the diagonal

15^2 + 15^2 = c^2

c= sqrt(15^2 +15^2) = 21.21 feet      she needs TWO of these   so  42.42 ft    added to the 60 ft above results in   102.42 ft     

each roll is 20 feet, so she will need  102.42 ft  / 20ft/roll = 5.12 rolls  ~~~ 6 rolls
