let
x--------> the length side of the legs of a right triangle
H------> hypotenuse
we /know that
in a right triangle
Applying the Pythagorean Theorem
H²=x²+x²------->H²=2x²-----> solve for x-------> x=H/√2
H=7 m
so
x=7/√2------->(7√2) /2 m------> 4.9497 m
the answer is
in simplified radical form------> (7√2) /2 m
as a decimal rounded to four places-------->4.9497 m
