Solution:
As per the problem we have
Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft.
As we know from the Pythagoras theorem in a right angled Triangle
Square of hypotenuse=Sum of the square of rest of the two sides
So we can write , if C represents the hypotenuse
[tex] C^2=1^2+3^2\\
\\
C^2=1+9\\
\\
C^2=10\\
\\
\text{take square root on both the sides we get}\\
\\
\
C=\sqrt{10}\\ [/tex]
Hence his answer was not correct
