Find the length of the diagonal of a rectangle, whose adjacent sides are $\left(2x+8\right) \mathrm{cm}, \left(2x+1\right) \mathrm{cm}$ and perimeter is $34 \mathrm{cm}$, also find its sides.

In the given figure, $ABCD$ is a trapezium, find the values of $x$, $y$ and $z$.

If $PQRS$ is a kite and $\angle SPQ=40°$ then find $\angle PSQ$ and $\angle PQS$.

All trapeziums are kites.

Diagonals of a rectangle intersect each other at right angle.

The perimeter of a parallelogram is $94 \mathrm{m}$. If the longer side is $8 \mathrm{m}$ greater than the two times of the shorter side, then find the length of the sides of the parallelogram.
