scalene triangles
Any two figures that total 17 ie from 1 x 16 up to 8 x 9
Yes, that is certainly possible.
An isosceles trapezium.
Eight 25 x 8 = 200 as 100 cm = 1 M
An iscoceles is : 2 sides are equal lenghts and 2 equal angles

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
Let the base be x and the height be x because their lenghts will be the same as it is a 45-45-90 triangle: 1/2*base*height = area 1/2*x*x = 32 1/2*x2 = 32 Multiply both sides by 2 and then square root both sides: x = 8 cm Use Pythagoras' theorem: 82+82 = 128 and the square root of this is 11.3137085 Therefore: hypotenuse = 11.314 cm correct to 3 decimal places
