Question

The area of the triangle is 28.7 square centimeters. What is the base length of the triangle in centimeters?

Answer 1

In order to derive the base of a triangle from its area, you need its height as well.

In fact, if we solve the area formula for the base, we have

`A=(bh)/(2) \iff 2A = bh \iff b=(2a)/(h)`

So, the base length would be

`b=(2\cdot 28.7)/(h) = (57.4)/(h)`

where h is the height relative to the base you're interested in.
