5.8788m

The altitude of the triangle to the selected base.

Altitude hₐ (to side a)5.8788m
Altitude hᵇ (to side b)4.899m
Altitude hᶜ (to side c)4.1991m
Area14.6969m²
Perimeter18m

The altitude is 5.8788 m.

  • The three altitudes are hₐ = 5.879 m (to side a = 5 m), hᵇ = 4.899 m (to side b = 6 m), and hᶜ = 4.199 m (to side c = 7 m).
  • The shortest altitude is 4.199 m and the longest is 5.879 m. The longest altitude always drops to the shortest side.
  • You can verify: Area = ½ × base × height. Plug in any base and its corresponding altitude and you will get 14.697 m² each time.

Next stepTo find the area from this height, multiply the base by the height and divide by 2. Need the full triangle solution? Try a triangle solver that finds all angles and sides.
