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.
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 similar rectangles have the widths 16m and 14cm what is the ratio of the perimiters?
Only if they both have the same ratio of length to width. Since every square has the same ratio of length to width ( it's 1 ), all squares are similar. Gee, when you think about it, every regular polygon is similar to every other regular polygon with the same number of sides. I never realized that.
It must be 0. Every rectangle can be flexed into a different parallelogram by altering one of its angles to an angle in the range (0, 90). Therefore there are infinitely many parallelograms corresponding to each rectangle. That is, the ratio for each rectangle is 1 : infinity, which is 0. Therefore that the answer for all rectangles and parallelograms is also 1 : infinity = 0.
If you are given two similar rectangles, one with all measurements and the other with only one, you first need to find the conversion ratio. Let's call the rectangle that you know everything about, rectangle A, and the other rectangle B. You take the ratio of the side of rectangle B to rectangle A. You then multiply the length of rectangle A by this value, to find the length of rectangle B.
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.
If you are trying to find the ratio of the lengths of two similar rectangles, divide the length of one side of one rectangle by the corresponding side length of the other rectangle. To find the ratio between their volumes, divide the volume of one rectangle by the volume the other rectangle. To find volume, multiply the width of the rectangle by the length of the rectangle.
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?
yes, all rectangles are in fact congruent. they're all congruent because its a ratio of sizes. if u have a rectangle with a length of 5 and a width of 2.5, and an another rectangle with a length of 10 and a width of 5, u have a ratio of sixes. the ratio would be 1:2. hope it helps (:
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.
If two similar rectangles have the widths 16m and 14cm what is the ratio of the perimiters?
It depends on whether the side length of 3 is the smaller or the larger of the two sides of the second rectangle. that is, is the 3 related to the 8 or the 17.
Only if they both have the same ratio of length to width. Since every square has the same ratio of length to width ( it's 1 ), all squares are similar. Gee, when you think about it, every regular polygon is similar to every other regular polygon with the same number of sides. I never realized that.
If two rectangles are similar, they have corresponding sides and corresponding angles. Corresponding sides must have the same ratio.
The ratio of 25-ft to 20-ft is 5/4 or 1.25 .But ... knowing the perimeters alone is not enough informationto guarantee that the two figures are similar.-- They could be two rectangles, one measuring 25-ft by 1-ft, the other measuring 4-ft by 5-ft.Those are not similar rectangles.-- They could even be one rectangle and one triangle ... definitely not similar.
It must be 0. Every rectangle can be flexed into a different parallelogram by altering one of its angles to an angle in the range (0, 90). Therefore there are infinitely many parallelograms corresponding to each rectangle. That is, the ratio for each rectangle is 1 : infinity, which is 0. Therefore that the answer for all rectangles and parallelograms is also 1 : infinity = 0.
