The height of the rectangle is 8.5 m, the width is 12.6 m, the height of the hole made in rectangle 4

The height of the rectangle is 8.5 m, the width is 12.6 m, the height of the hole made in rectangle 4, the width of the hole is 2.5. Calculate what percentage of the total area the hole occupies.

Find the total area and area of the hole:
S1 = 8.5 * 12.6 = 107.1 (m ^ 2) – the total area of the rectangle;
S2 = 4 * 2.5 = 10 (m ^ 2) – hole area.
Let’s calculate how many percent of the total area the hole takes. For this:
S2 / S1 = 10 / 107.1 = 0.093 = 9.3%
Answer: 9.3%.
