If the ratio of the side lengths of two similar rectangular prisms is 3/5, what would be the ratio of their areas

Given:

Ratio of the side lengths of two similar rectangular prisms is .

To find:

The ratio of their areas.

Solution:

If two figures are similar then their areas are proportional to the squares of their corresponding sides.

          ...(i)

Where, are areas and are corresponding sides.

It is given that ratio of the side lengths of two similar rectangular prisms is . It means, .

Using (i), we get

Therefore, the ratio of their areas is . It is also written as 9:25.

they charge the same amount at 20 minutes.

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
