Suppose each square in the shown grid is one by one square centimeter. What is the area of the colored shape?

Since we know that each of these squares is one square centimeter, the only thing we need to do to find the area is count the number of colored squares. One, two, three, four, five, six, seven, eight, nine, 10, 11. There are 11 colored squares. Each square has an area of one centimeter square, so we can multiply 11 times one centimeter squared. 11 times one equals 11.

The area of this colored figure is 11 square centimeters.
