Question

1. 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. (wip) 5 what percentage of the wall was painted? 6.4e

Explanation:

Step1: Calculate the total number of squares

The wall is a rectangle with \(8\) rows and \(5\) columns. Using the formula for the area of a rectangle \(A = length\times width\), the total number of squares \(n_{total}=8\times5 = 40\).

Step2: Count the number of shaded squares

By counting, the number of shaded squares \(n_{shaded}=19\).

Step3: Calculate the percentage

The formula for percentage is \(P=\frac{n_{shaded}}{n_{total}}\times100\%\). Substitute \(n_{shaded} = 19\) and \(n_{total}=40\) into the formula: \(P=\frac{19}{40}\times100\%= 47.5\%\).

Answer:

\(47.5\%\)
