Question

A local artist has made a temporary painting on the concrete surface of the school playground. It completely covers a 70 by 66 m² area of the playground. If 22% of the painting is blue, and 21% is red, how many m² of the painting are neither blue nor red?

Answer 1

2633.4 meters²

Explanation:

I'm going to assume you didn't mean to put 66 m²

70 m × 66 m = 4620 m²

22% of 4620 m² is 1016.4 m²

21% of 4620 m² is 970.2

4620-1016.4-970.2 = 2633.4 meters² that are not blue or red.
