Whatever the ratio of perimeters of the similar figures, the areas will be in the ratios squared. Examples: * if the figures have perimeters in a ratio of 1:2, their areas will have a ratio of 1²:2² = 1:4. * If the figures have perimeters in a ratio of 2:3, their areas will have a ratio of 2²:3² = 4:9.
P= Add all sides A= LxW
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.
The ratio is 16 to 81.
is it 3:5 and 3:5
it has helped in finding the perimeters and areas of circle.
There is no particular reason. In fact, in general, two shapes will have different areas or perimeters or both.
It's very important such as finding out areas and perimeters, etc. Also important is grammar, you should learnt hat as well as math.
The areas are different.

Yes.
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
Perimeters = sum of sides added together
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.

The ratio of their perimeters is also 45/35 = 9/7. The ratio of their areas is (9/7)2 = 81/63
It is 0.6046 : 1 (approx).
