Answer:
To calculate the percentage represented by the shaded area in the first square model partitioned into 2 equal parts, where 2 parts are shaded, we can see that the shaded area represents 2 out of 2 equal parts, which is 100% since both parts are shaded.
In the second square model partitioned into 2 equal parts, where 1 part is shaded, the shaded area represents 1 out of 2 equal parts, which is equivalent to 50%.
Therefore, the percentage represented by the shaded area overall is the average of 100% and 50%, which is (100% + 50%) / 2 = 75%.
So, the shaded area represents 75% of the whole.
