Question 257382: find the diagonal of a square with perimeter 20 inches
Answer by drk(1908) (Show Source): You can put this solution on YOUR website!
IF the perimeter = 20, then a side = 5.
using Pythagorean theorem, we get
a^2 + b^2 = c^2
or
5^2 + 5^2 + c^2
25 + 25 = c^2
50 = c^2
c = sqrt(50) = 5sqrt(2).
This is the diagonal
