Answer 2

Answer:

2m.

Step-by-step explanation:

The ramp with the base and height form a right-angled triangle.

If the inclination of the ramp is not more than 30° (say equals to 30°), then we have to calculate the length of the ramp (i.e. length of the hypotenuse of the right- angled triangle).

Using the trigonometrical function, Sin 30°= perpendicular/hypotenuse

⇒ Sin 30° = height of ramp / length of ramp

⇒1/2=1/ length of the ramp {Since, Sin 30°=1/2 and the height of the ramp is equal to 1 m}

⇒Length of the ramp =2 m.

Hence, if the ramp slope is not more than 30°, then length of the ramp will have to be not more than 2 m. (Answer)
