9:25
7:3
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
The ratio is 19/9.
If the lengths are in the ratio 3:5, then the surface areas are in the ratio 9:25.
The ratio of area is 4 : 81.
is it 3:5 and 3:5
If the ratio of similarity is 310, then the ratio of their area is 96100.
7:3
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
The ratio of areas is 18:50 which simplifies to 9:25 or 9/25 So the ratio of their sides is sqrt(9/25) = sqrt(9)/sqrt(25) = 3/5 That is, the linear ratio is 3:5
Measure any two corresponding edges. The ratio of these edges is the similarity ratio.
For two similar polygons, the ratio of their areas is equal to the square of the ratio of their corresponding side lengths. Given the similarity ratio of the smaller polygon to the larger polygon is 2:3, we calculate the area ratio as follows: ( \left(\frac{2}{3}\right)^2 = \frac{4}{9} ). Therefore, the ratio of the areas of the smaller polygon to the larger polygon is 4:9.
3:1
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.
The similarity ratio is 1:4.
If two solids are similar and the ratio of the lengths of their edges is 29, the ratio of their surface areas will be the square of the ratio of their lengths. Therefore, the ratio of their surface areas is (29^2), which equals 841. Thus, the ratio of the surface areas of the two solids is 841:1.
The ratio is 19/9.
