A triangle has an area of 8m^2+12m square units. Which expression represents the base of a triangle?

Question

anonymous · Answer

oh really there is  now way of knowing unless you have a picture.  they want you to say 
$$8m^2+12m=4m(m+3)$$

anonymous · Answer

and area is $$\frac{1}{2}bh$$

anonymous · Answer

so $$\frac{1}{2}bh=4m(m+3)$$
$$bh=8m(m+3)$$

Is there any information what kind of triangle do you have? right triangle? equilateral?

anonymous · Answer

some math teacher made up this problem

anonymous · Answer

like that geometric series one where the first term was $$\sqrt{x}$$ and the third term was $$4\sqrt{5}$$ and you were supposed to deduce r  as if it was possible
