To solve the problems regarding the rhombus, we will follow these steps:

### Problem 7: Area of a Rhombus

**Known Conditions:**
- Each side of the rhombus (s) = 30 cm
- One diagonal (d₁) = 48 cm

**Step 1: Find the other diagonal (d₂)**

In a rhombus, the diagonals bisect each other at right angles. We can use the Pythagorean theorem to find the length of the other diagonal.

Let $$ d_2 $$ be the length of the other diagonal. The relationship can be expressed as:
$$
s^2 = \left(\frac{d_1}{2}\right)^2 + \left(\frac{d_2}{2}\right)^2
$$

Substituting the known values:
$$
30^2 = \left(\frac{48}{2}\right)^2 + \left(\frac{d_2}{2}\right)^2
$$

Calculating:
$$
900 = 24^2 + \left(\frac{d_2}{2}\right)^2
$$
$$
900 = 576 + \left(\frac{d_2}{2}\right)^2
$$
$$
\left(\frac{d_2}{2}\right)^2 = 900 - 576
$$
$$
\left(\frac{d_2}{2}\right)^2 = 324
$$
$$
\frac{d_2}{2} = 18 \quad \Rightarrow \quad d_2 = 36
$$

**Step 2: Calculate the area (A) of the rhombus**

The area of a rhombus can be calculated using the formula:
$$
A = \frac{d_1 \cdot d_2}{2}
$$

Substituting the values:
$$
A = \frac{48 \cdot 36}{2}
$$
$$
A = \frac{1728}{2} = 864 \text{ cm}^2
$$

### Problem 8: Area of a Rhombus

**Known Conditions:**
- Each side of the rhombus (s) = 15 cm
- One diagonal (d₁) = unknown (not provided in the prompt)

Since the second diagonal is not provided, we cannot calculate the area without additional information. If you can provide the length of the second diagonal or any other relevant information, I can help you find the area.

### Summary of Results
- **Area of Rhombus ABCD**: $$ 864 \text{ cm}^2 $$
- **Area of the iron sheet rhombus**: Requires additional information about the diagonals.
- **Problem 7**: The area of rhombus ABCD is 864 cm². - **Problem 8**: Cannot determine the area without the length of the second diagonal.
