If 3,5 be the distances between the parallel sides and `30^@` is the angle between two adjacent sides of a parallelogram then its area is

If two adjacent sides of a parallelogram are 3.5 , 6 cms . Then its perimeter is ___.

The area of a trapezium -shaped field is 720 m^(2) , the distance between the two parallel sides is 20 m and the length of one of the parallel sides is 35 m. The length of the other parallel side is

The area of a trapezium-shaped field is 720m^(2) , the distance between the two parallel sides is 20 m and the length of one of the parallel sides is 35 m. The length of the other parallel side is

The parallel sides of a trapezium are in the ratio 3:4. If the distance between the parallel sides is 9 dm and its area is 126 dm^(2) , find the lengths of its parallel sides.

Find the distance between the two parallel sides of a trapezium if the area of the trapezium is 500 sq m and the two parallel sides are equal to 30 m and 20 m, respectively.

ABCD is a parallelogram having adjacent sides AB = 35 cm and BC = 28 cm . If the distance between its longer sides is 8 cm , find : (i) the area of the parallelogram (ii) the distance between its shorts sides

The vectors AB = 3i - 2j + 2k and BC = - I - 2k are the adjacent sides of a parallelogram. The angle between its diagonals is
