Answer:

h = 34.7 units

Step-by-step explanation:

Write out the formula for the area of a triangle of base b and height h:

A = (1/2)(b)(h)

It is the height, h, that we want to calculate.  Solve the above equation for h:

  2A

--------- = h

    b

Now plug in '260 square units' for A and '15 units' for b:

      2(260 square units)

h = ------------------------------- = 34.67 units

                  15 units

Rounding off this result to the nearest tenth, we get  h = 34.7 units
