What is the area of the shaded shape?

Question

A grid is labeled a square equals one square unit. There are 10 rows and 10 columns of squares. Three rows of 10, 1 row of 8, 1 row of 6, 1 row of 4, and 3 rows of one are shaded.

Answer 1

To find the area of the shaded shape, we need to count the number of squares that are shaded.

Starting from the bottom, the first row of 3 squares is shaded. The next row of 8 squares is also shaded. Then, the next row of 6 squares is shaded. The row after that has 4 squares shaded. Finally, there are three rows of one square each that are shaded.

So, the total number of shaded squares is 3 + 8 + 6 + 4 + 3 = 24.

Therefore, the area of the shaded shape is 24 square units.
