From the information given, the leg of the triangle measures 3 cm and the other leg measures 6 cm. The length of the hypotenuse is unknown.
Let the hypotenuse be c
Let one leg of the triangle be a
Let the other leg of the triangle be b
We use the formula : c² = a² + b²
c² = 3² + 6²
c² = 9 + 36
c² = 45
c = √45
c = 6.70
Therefore, the length of the hypotenuse is 6.7 cm
