An access ramp enters a building 1 meter above ground level and starts 4 meters from the building. How long is the ramp? If it is not possible, write “not possible” and explain why it is not possible.

Answer 1

Since you have a right triangle, you can use the Pythagorean theorem.

a^2 + b^2 = c^2
1^2 + 4^2 = c^2
1 + 16 = c^2
17 = c^2
4.123 = c
