The area of an isosceles trapezoid is $77$ square inches, the height measures $4$ inches and the legs are $5$ inches long. Find the lengths of the bases.

The lengths of the parallel side of a trapezium are in the ratio $3:2$ and the distance between them is $10 \mathrm{cm}$. If the area of the trapezium is $325 {\mathrm{cm}}^2$, find the length of the parallel sides.

$ABCD$ is a trapezium in which $AB\parallel CD, AD\perp DC, AB=20 \mathrm{cm}, BC=13 \mathrm{cm}, \mathrm{and}\mathit{ }DC=25 \mathrm{cm}$. Find the area of the trapezium in ${\mathrm{cm}}^2$.

Find the area of a trapezium whose parallel sides are $AB \mathrm{and} CD$ and $AB=12 \mathrm{cm}$ and $CD=36 \mathrm{cm}$ and the non parallel sides are $BC=15 \mathrm{cm}$ and $AD=15 \mathrm{cm}$ in ${\mathrm{cm}}^2$ (Draw $AE\parallel BC$).

The area of a trapezium is $165 {\mathrm{cm}}^2$ and its height is $10 \mathrm{cm}$. If one of the parallel sides is double the other, Find the two parallel sides.

The area of a trapezium with equal non-parallel sides is $168 {\mathrm{cm}}^2$. If the length of the parallel sides are $36 \mathrm{m} \mathrm{and} 20 \mathrm{m}$. Find the length of the non-parallel sides.

Find the area of a trapezium if its parallel sides are of length $15 \mathrm{cm}$ and $11 \mathrm{cm}$ and distance between parallel sides is $9 \mathrm{cm}$.

Find the height of a trapezium, if its area is $156 {\mathrm{m}}^2$ and sum of the parallel sides is $9 \mathrm{m}$. (upto two decimal places)

If the height and area of the trapezium are $11 \mathrm{dm} \mathrm{and} 396 {\mathrm{dm}}^2$ and the parallel sides are in the ratio$3:5$, find their length.
