Find the area of the rhombus in ${\mathrm{cm}}^2$, length of whose diagonals are given here.

Find the area of the rhombus in ${\mathrm{m}}^2$, length of whose diagonals are given here.

The length of one of the diagonals of a rhombus is $5 \mathrm{cm}$ less than the length of the other diagonal. The area of the rhombus is $33 {\mathrm{cm}}^2$. Find the length of each diagonal.

A rhombus has perimeter of $100 \mathrm{m}$ and a diagonal $30 \mathrm{m}$ long. Find the area of the rhombus (in ${\mathrm{m}}^2$).

The floor of a building consists of $2000$ tiles which are rhombus shaped and each of its diagonals are $40 \mathrm{cm}$ and $25 \mathrm{cm}$ in length. Find the total cost (in $₹$) of polishing the floor if the cost per ${\mathrm{m}}^2$ is $₹15$.

Find the altitude of the Rhombus (in $\mathrm{cm}$, correct to one decimal place) whose area is $315 {\mathrm{cm}}^2$ and one diagonal is $30 \mathrm{cm}$.

Find the area of a tile in the shape of a Rhombus whose diagonal are of $24 \mathrm{cm}$ and $10 \mathrm{cm}$. Also, find the cost of $500$ tiles if the cost of $1 {\mathrm{cm}}^2$ of the tile is $₹2$.

Find the perimeter and area of Rhombus in which the diagonals are $6 \mathrm{cm}$ and $8 \mathrm{cm}$.
