Question
The square below represents one whole.An array with 10 columns and 10 rows that represents 1 whole. 9 rows of 10 are shaded. 1 row of 2 is shaded.What percent is represented by the shaded area?
Solution
The square represents 1 whole, which is divided into 100 parts (10 rows and 10 columns).
The shaded area consists of 9 full rows of 10 and 1 row of 2.
So, the total shaded area is (9*10) + 2 = 92 parts out of 100.
To find the percentage, we divide the shaded area by the total area and multiply by 100.
So, the shaded area represents 92% of the total area.
