Question

The length of the base of a triangle is twice its height. if the area of the triangle is 169 square​ kilometers, find the height

Answer 1

13 km

Explanation:

The area formula for a triangle is ...

A = (1/2)bh

We are told that b=2h, so this becomes ...

A = (1/2)(2h)(h) = h²

Substituting the given area, we can find h:

169 km² = h²

(√169) km = h = 13 km

The height is 13 km.
