Maharashtra Board Solutions for Exercise 2: Practice Set 15.2

Lengths of the diagonals of a rhombus are $15 \mathrm{cm}$ and $24 \mathrm{cm}$, if its area is $k {\mathrm{cm}}^2$ then find $k$.

Lengths of the diagonals of a rhombus are $16.5 \mathrm{cm}$ and $14.2 \mathrm{cm}$. If its area is $k {\mathrm{cm}}^2$, then find the value of $k$. (Express your answer as decimal number)

If the perimeter of a rhombus is $100 \mathrm{cm}$ and the length of one diagonal is $48 \mathrm{cm}$, then the area of the quadrilateral is $k {\mathrm{cm}}^2$. Now, find the value of $k$.

If length of a diagonal of a rhombus is $30 \mathrm{cm}$ and its area is $240 \mathrm{sq} \mathrm{cm}$, then the perimeter is $k \mathrm{cm}$. Find the value of $k$.
