If two polygons are similar then the ratio of their perimeter is equal to the ratios of their corresponding sides lenghts?
parallelogram
no
9 meters
13 feet
If it has 2 opposite parallel sides of 10 cm and 2 opposite parallel sides of 5 cm then its perimeter is the sum of the 4 sides which is 30 cm
Yes, that is certainly possible.
irregular quadrilateral
If you mean an isosceles trapezoid with parallel sides of 18 cm and 27 cm then the length of the 4th sides is 2 cm
