Andes -  Near a 'subduction' zone. Himalayas - 2 continents colliding. Aleutian - 2 ocean plates colliding. Grand Tetons - 'Plates spreading'.

Explanation:

'Andes Mountains' were formed by the subduction of the oceanic plate under the continental plate. 'Himalayas' were formed by the "collision of the Indian plate" and "the Eurasian plate". Aleutian islands were formed due to the "subduction of the Pacific plate" under the "North American plate". Grand Tetons were a result of spreading and thinning of the Earth's crust in the region.

H=   2(area/a+b)h= 2(144/a+b)h= 2(144/18+18)h= 2(144/36)h= 2(4)h=8
