Question 1153623
The owners of a house want to convert a stairway leading from the ground level to their back porch into a ramp.
 The porch is 3 feet off the ground, and due to the building regulations, the ramp must start 12 feet away from the base of the porch.
 How long will the ramp be? Round answer to two decimal places.
:
A right triangle will be formed: a^2 + b^2 = c^2, where
a = 3
b = 12
c = the hypotenuse which is the ramp
:
c^2 = 3^2 + 12^2
c^2 = 9 + 144
c^2 = 153
c = {{{sqrt(153)}}}
c = 12.37ft is the length of the ramp
