the formula for the area of a rhombus with diagonals of lengths c and d is A=1/2cd

Yes, that's correct! The formula for the area \( A \) of a rhombus when the lengths of its diagonals are given as \( c \) and \( d \) is:

\[
A = \frac{1}{2} \cdot c \cdot d
\]

### Explanation:
The diagonals of a rhombus bisect each other at right angles, and the area of a rhombus can be thought of as the sum of the areas of the four right triangles formed by the diagonals. The product of the diagonals \( c \) and \( d \) gives twice the area of the rhombus, so dividing by 2 gives the actual area.

1. How does the formula for the area of a rhombus relate to that of a rectangle?
2. What is the relationship between the diagonals of a rhombus and its side length?
3. How can we calculate the diagonals of a rhombus if only the area and side length are given?
4. Can this formula be used for squares, which are a special type of rhombus?
5. How can you derive this formula using the properties of triangles?

### Tip:
If you know the side length of the rhombus, you can also find the diagonals by using trigonometry, especially if angles are involved!
