How Can I Find the Center of Gravity for a Uniformly Distributed Mass?

[bmandrade]

Homework Statement

i need to find the center of gravity of the attached shape

Homework Equations

i know that in order to find center of gravity i can use the equation $$\Sigma$$m_ix_i$$/$$$$\Sigma$$m_i but for the case it doesn't work becasue i don't have mass of this shape it just says that the mass is uniformly distributed

The Attempt at a Solution

I have no clue how to solve it

Find the centroid of the shape using areas instead of mass. When the mass is uniformly distributed, the results are the same. Or you could just assume a mass density of m per sq.cm, and the m's will cancel, right?
