Perimeter will scale by the same factor. Area of the new figure, however is the original figures area multiplied by the scale factor squared.

they are related when you can multiply or divide them together and get a whole number

The area of similar figures is proportional to the square of any linear measurement. (And all linear measurements are directly proportional.) Thus, if the ratio of the perimeters is 5/4, the ratios of the lengths of sides is also 5/4. The ratio of the areas, on the other hand, is (5/4)2, so you can simply multiply the area of the smaller square by this factor.
Yes, if the angles are the same the two figues are similar. The side lengths don't have to be the same.
All congruent figures are similar figures, and have identical sizes.
The areas are different.
if you add up all the sides but in a smart way
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.

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.
Their perimeters are in 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.
Since this is extra credit you need to do the work. Wiki will not help you cheat.

The precision of a measurement can be determined by the number of significant figures or decimal places in the measured value. A measurement with more significant figures or decimal places is considered more precise. Additionally, repeated measurements that yield similar results indicate a higher level of precision.
Congruent figures are always similar. However, similar figures are only sometimes congruent.
