# Math Help - Comparing Area Formulas

1. ## Comparing Area Formulas

Use a geometry formula to calculate the are of the region...

I know that the area of a triangle is A=(1/2)(b)(h)

The triangle equation that is given is y=(h/b)(x)

My question is how to calculate the area of the region with A=(1/2)(b)(h)

2. I don't really get your question.
I would tell you to see that you have a rectangle of area $hb$ that is cut in two pieces.
Else $\int_0^b h/b x = h/b \cdot b^2/2 = hb/2$
