Question 310894
As per the qs "Two legs of a right triangle are the same." which means it is an isoceles rt angled triangle.

Let the sides be x
Hypotenuse= 6 mts

therefore we can write

x^2 + x^2 = 6^2
or, 2x^2=36
or, x^2 = 18 (Divided either sides by 2)
or, x = +-sqrt(18)

As x can only be positive we will take the positive value which is

{{{sqrt(18)= 3sqrt(2)}}}
