2x^2=100
x^2=50
x^2=25*2
x=5sqrt(2)
perimeter=10sqrt(2)+10

Hi,

If a right triangle has a hypotenuse of 10 ft and it appears to be a 45-45-90 triangle(2 equal sides highlight%28x%29)

then what is the perimeter?  x^2 + x^2 = 10 , x = sqrt%285%29

P = 10ft + 2sqrt%285%29ft = 14.47 ft(rounded to 2 decimal points)
