I guess you mean the ratio of the areas; it depends if the 2 rectangles are "similar figures"; that is their matching sides are in the same ratio. If they are similar then the ratio of their areas is the square of the ratio of the sides.

What is meant by a ratio of 2 to 1?

That, for every two of something, there is one of something else. For example, if the ratio of men to women at my party is 2:1, there are two men for every one woman.


What is the missing length of two similar rectangles if the first has length n inches and width 16 inches and the second has length 15 inches and width 12 inches?

20 inches


Two triangular prisms are similar. The perimeter of each face of one prism is double the perimeter of the corresponding face of the other prism. How are the surface areas of the figures related?

The ratios of areas are the squares of the ratio of lengths (and the ratio of volumes are cubes of the ratio of lengths). As the perimeter of the second is twice the perimeter of the first, each length of the second is twice the length of the first, and so the ratio of the lengths is 1:2 Thus the ratio of the areas is 1²:2² = 1:4. Therefore the surface area of the larger prism is four times that of the smaller prism.


Is it true that the greater the perimeter the greater the area?

No, in general that is not true. For two similar figures it is true. But you can easily design two different figures that have the same perimeters and different areas, or the same area and different perimeters. For example, two rectangles with a different length-to-width ratio.


What is the determinant of a two-by-two matrix?

To find that, you multiply the first element of the first row by the second element of the second row. You also multiply the first element of the second row with the second element of the first row. Then you subtract the products not add them.

What would the ratio of a two rectangles be if one rectangles width is 24Cm and length 30Cm the other rectangle is width of 36 Cm length of 42 Cm?

These are not similar rectangles so there is no obvious candidate for the ratio. Is it ratio of lengths (sides, perimeter, diameter), or ratio of area?


If two rectangles are similar then the corresponding sides are?

If two rectangles are similar, they have corresponding sides and corresponding angles. Corresponding sides must have the same ratio.


What does value of a ratio mean in math?

The value of a ratio - of two numbers - is the value of the first divided by the second.


Is the ratio of length to width for these two rectangles proportional?

To determine if the ratio of length to width for two rectangles is proportional, you need to compare the ratios of their lengths to widths. If the ratios are equal, then the rectangles are proportional. For example, if Rectangle A has a length of 10 units and a width of 5 units (ratio of 10:5 or 2:1), and Rectangle B has a length of 20 units and a width of 10 units (ratio of 20:10 or 2:1), then the rectangles are proportional because the ratios are equal.


How do you determine if rectangles are Simular?

If the 'ratio' (length/width) of one rectangle is the same number as (length/width) of the other one, then the two rectangles are similar.


How do you compare a ratio using division?

Divide the first ratio by the second. If the answer is less than 1 then the first ratio is smaller. If the answer is equal to 1 then the two ratios are equal. If the answer is greater than 1 then the first ratio is larger.

It is simply the first measurement divided by the second, expressed with their measurement units as a ratio.


What is a ratio whose second term is 100?

A ratio is a comparison of two quantities. When the second term of a ratio is 100, it means that the ratio is comparing the first term to 100. For example, if the ratio is 1:100, it means the first term is 1 and the second term is 100. Ratios with a second term of 100 are often used to express proportions or percentages.

What relationship exists between two variable when their ratio is a constant?

Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.


What is its the width of 2 rectangles that the areas are 15cm2 and 60cm2 the lengt of the first rectangle is 5cm?

I can give the width of one of the rectangles. The first rectangle of area 15 cm2 and length of 5 cm has width of 3 cm. It is impossible to know the width of the other rectangle of area 60 cm2. However, if you had said that the two rectangles were similar, then the dimensions of the second rectangle would be 10 cm X 6 cm. But you didn't say that the two rectangles were similar; so there are infinite possibilities of what the dimensions of the second rectangle might be.
