Examples with solutions for Estimation: Approximate the area of the colored part of the shape

Exercise #1

What percentage does the shaded area of the figure represent?

Video Solution

Step-by-Step Solution

It can be said with certainty that the shaded area is larger than half of the shape.

That is, the shaded part is more than 50%.

Therefore, we can disregard answers B and D.

The unshaded part is greater than 1% of the figure; it is not possible for 100 such parts to form the complete shape, therefore, we can disregard answer C.

Therefore, the correct answer must be 80%.
