Question

the length of the base of a triangle is twice its height. if the area of the triangle is 4 square kilometers, find the height

Answer 1

Let the height = x

Base = 2x

Area of triangle = (1/2)*base*height

Area = (1/2)*2x*x = 4 

x² = 4

x = √4

x = 2

Height = 2 km.

Answer 2

The height is 2 kilometers
