By Pythagorean Theorem: d^2 = 5^2 + 12^2
d^2 = 25 + 144 = 169
d=13
The diagonal length of the floor is 13 feet.

the floor?
this is d = â(L^2 * w^2) = â(12^2 * 5^2) = â169 = 13

hello...first get the diagonal of the floor,using pythagorean theorem you can get d=13, then the diagonal length of the room using 13(the diagonal of the floor ) and 8 the length of the wall using pythagorean theorem and you'll have sqrt of 233 or 15.26433
try it ....hope its coorect..

you have rectangle 5x12
a=5
b=12
c=?
we are looking for c
We use the equation:
c= â(a² +b²)
Replace those values we know into the equation:
c= â(a² +b²)
c= â(5² +12²)
c= â(25+ 144)
c= â169
c=13
Answer: 13
Hope that was helpful! :D
