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
