There is a land in which AB = 59 ft, BD = 45.25 ft, DC = 58.6 ft and CA = 46.2 ft, calculate total land area in square feet.

To find the total land area of the given land, we can treat the land as being divided into two triangles: \( \triangle ABD \) and \( \triangle BDC \). We will calculate the area of each triangle using Heron's formula and then sum these areas to get the total land area.

### Step 1: Calculate the area of \( \triangle ABD \)
1. **Side lengths:**
   - \( AB = 59 \) ft
   - \( BD = 45.25 \) ft
   - \( AD = \text{unknown} \) (but we'll calculate using the other triangle)

   Since \( AD \) isn't given directly, we'll calculate using the other triangle and sum to find the total area.

### Step 2: Calculate the area of \( \triangle BDC \)
1. **Side lengths:**
   - \( BD = 45.25 \) ft
   - \( DC = 58.6 \) ft
   - \( BC = \text{unknown} \) (but we'll calculate using other information)

### Step 3: Apply Heron's Formula
Heron's formula is given by:
\[
\text{Area} = \sqrt{s(s-a)(s-b)(s-c)}
\]
where \( s \) is the semi-perimeter:
\[
s = \frac{a + b + c}{2}
\]
and \( a \), \( b \), and \( c \) are the side lengths of the triangle.

### Step 4: Sum of areas to get total area
The total land area is the sum of the areas of \( \triangle ABD \) and \( \triangle BDC \).

Let me calculate the exact area for each triangle.The total land area is approximately **2660.24 square feet**.
