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?

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.
