A skateboard ramp cover a horizontal distance of 17 feet and raises to 4 feet above the ground. what is the length of the skateboard ramp?

To find the length of the skateboard ramp, we need to look at the triangle where the length of the skateboard ramp is a hypotenuse, a horizontal distance is a leg and a vertical distance is a leg also. So we can use Pythagorean theorem.

c² = a² + b²

c² = 17² + 4² = 305

c=√305≈17.46

Answer is 17.46 feet.
