Find the area of the trapezium whose parallel sides are of length $12 \mathrm{cm}$ and $15 \mathrm{cm}$ and the distance between them is $15 \mathrm{cm}$.

Find the area of the trapezium whose parallel sides are of length $17.2 \mathrm{cm}$ and $6.5 \mathrm{cm}$ and the distance between them is $0.24 \mathrm{m}$.

Find the distance between the parallel sides of length $25 \mathrm{m} \mathrm{and} 36 \mathrm{m}$ of the trapezium whose area is $366 {\mathrm{m}}^2$.

Area of a trapezium is $4875 {\mathrm{cm}}^2$ and one of whose parallel sides is $3.02 \mathrm{m}$ in length. If the distance between the parallel sides is $25 \mathrm{cm}$, find the other parallel side.

The distance between the parallel sides of a trapezium which are in the ratio $3:5$ is $22 \mathrm{cm}$. If the area of the trapezium is $1100 {\mathrm{cm}}^2$, find the parallel sides of the trapezium.

One parallel side of a trapezium is double the other. The distance between the parallel sides is $\frac{1}{3}\mathrm{rd}$ of the smaller parallel sides. Find the length of the parallel sides of the trapezium, if its area is $98 {\mathrm{cm}}^2$.

The parallel sides of the trapezium are $7$ more and $7$ less than the distance between them. Find their lengths and the distance between them, if the area of the trapezium is $169 {\mathrm{m}}^2$.

An isosceles trapezium is such that its parallel sides are of lengths $24 \mathrm{cm}$ and $48 \mathrm{cm}$, respectively, whereas the non-parallel sides are each $37 \mathrm{cm}$ long. Find the area of the trapezium.
