The sides of the rectangle are 11.8 cm and 5 cm, and the sides of the other are 13.6 cm and 6 cm.

The sides of the rectangle are 11.8 cm and 5 cm, and the sides of the other are 13.6 cm and 6 cm. Find the percentage of the area of the first rectangle from the area of the second, and round to hundredths of a percent.

Find the area of the first rectangle by multiplying its length by width:

11.8 * 5 = 59 (cm).

Then we find the area of the second rectangle, also multiplying its length by width:

13.6 * 6 = 81.6.

We divide the area of the first by the area of the second:

59: 81.6 = 0.723039.

To find out how much it is in percentage, multiply the result by 100:

0.723039 * 100 = 72.3039%.

Rounding up to hundredths of a percent, we get 72.30%.
