Work Step by Step

We first count all of the squares to find that there are 48 squares in the figure total. We now count red squares to find that there are 14 red squares in the figure. In order to find what percent of the figure is red, we divide 14 by 48 to get a decimal: .291667. We multiply this decimal by 100 to make it a percent, getting that 29.167 percent of the figure is red.
