Question

You are designing a skateboard ramp with a base of 12 meters long and 4 meters high. how long in feet is the incline of the ramp?

Answer 1

To answer this question you need to use the Pythagorean theorem. First you substitute the values for a and b. Usually, the value of c represents the hypotenuse in this case c represents the incline of the ramp. As you can see in the following calculations we set a to be the base of the ramp while b is the height of the ram.


`a^2+b^2=c^2 \\ c= √(12^2+4^2) \\ c= √(160) \\ c=3.556`

We get that the incline of the ramp is about 3.556 meters however we can round it up to be 4 meters. The final answer needs to be given in feet, and 1 meters is 3.28 feet. Therefore to get the answer in feet we do the following calculations:

`4 meter * (3.28 ft)/(1 meter) = 13.12 feet`

Therefore the ramp incline should be 13.12 feet.
