## Homework Statement

The machinist's square shown in the figure consists of a thin, rectangular blade connected to a rectangular handle. Determine the x and y coordinates of the center of gravity. Let the lower corner be x=0, y=0.

## Homework Equations

x_cg = (m_1 * x_1)+(m_2 * x_2).../(m_1+m_2+...)

y_cg = ...... (same thing, but y)

## The Attempt at a Solution

pI have gotten an answer, but it is not matching up with the back of the book. Here are the numbers I used to get my answer:

x_1 = 4cm

x_2 = 12cm

y_1 = 11cm

y_2 = 3.0cm

for x_cg I have: [(4cm*40g)+(12cm*80g)] / (40g+80g)= 9.3cm

for y_cg I have: [(11cm*40g)+(3.0cm*80g)] / (40g+80g)= 5.67cm

What did I do wrong? Thank you for any help!
