Hi,
Applying the Pythagorean Theorem{{{ highlight_green(a^2 + b^2 = c^2)}}} to find the length{{{ highlight_green(x)}}}of each leg for this right triangle
x^2 + x^2 =5^2
 2x^2 = 25
    x = {{{sqrt(25/2)}}}
    x = {{{5/sqrt(2)= 5sqrt(2)/2}}} (Tossing out the negative solution for unit measure)
P = {{{5 + 5sqrt(2)/2 + 5sqrt(2)/2 = 5 + 5*sqrt(2)}}}
