Question

A town recreation hall needs to build a ramp. The height of the ramp must be 2 ft. The ramp will start 6 ft. from the door. To the nearest tenth of a foot, how long will the ramp be?

Answer 1

The ramp will form a triangle with height 2ft and base 6ft.

The length of the ramp will be the hypotenuse of this triangle.
length² = height² + base²
length = √(height² + base²)
length = √(2² + 6²)
length = √(4 + 36)
length = √40
length = 6.3ft

Therefore, the ramp will be 6.3ft long.
