How come that the hypotenuse in the solution became 5m where it is 2.5m?

What is shown in the solution is slope. 1/2.5 = 2/5. If you are not used in solving with slope, go with angles.

Got it. Thank you

Great

Use your scientific calculator that is capable of displaying fraction. If you input 1/2.5 the calculator will output 2/5.
