Question

The shaded area on the grid represents the part of a rectangular wall that was painted. Each

small square on the wall has the same dimensions.
What percentage of the wall was painted?

Answer 1

60%

Explanation:

Answer 2

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

=
`\frac{\text{Painted squares}}{\text{Total squares}}* 100` =
`(24)/(40)* 100`

= 60%

Therefore, 60% of the wall is painted.
