Answer:
60% of the wall is painted.
Explanation:
From the picture attached,
There are total 40 squares. Out of 40 squares 16 squares are clear (not painted).
Hence painted squares on the wall = 40 - 16
= 24
Formula to calculate the percentage of painted squares is
=
=
![(24)/(40)* 100](https://img.qammunity.org/2021/formulas/mathematics/college/nu6n16ngs5h515ezz0fateduwsbpjobt6w.png)
= 60%
Therefore, 60% of the wall is painted.
