1. Determine the dimensions of the lot. Given the frontage is 20 meters, calculate the other side using the area:
\text{Area} = 20 \times x = 400
x = \frac{400}{20} = 20 \, \text{meters}
2. Calculate the perimeter of the lot:
\text{Perimeter} = 2 \times (20 + 20) = 80 \, \text{meters}
3. Calculate the total height of the wall:
\text{Total height} = 1.2 + 3.8 = 5 \, \text{meters}
4. Calculate the wall area excluding the gate:
\text{Wall area} = (\text{Perimeter} - \text{Gate width}) \times \text{Total height}
\text{Wall area} = (80 - 5) \times 5 = 75 \times 5 = 375 \, \text{sqm}
5. Calculate the cost of the wall:
\text{Wall cost} = 375 \times 750 = 281,250 \, \text{PHP}
6. Calculate total cost including the gate:
\text{Total cost} = \text{Wall cost} + \text{Gate cost}
\text{Total cost} = 281,250 + 50,000 = 331,250 \, \text{PHP}
7. Therefore, the total cost is:
\text{Php} \, 331,250.00
