1. The formula for the area of a triangle is given by:
A = \frac{1}{2} \times \text{base} \times \text{height}
2. Substitute the given values into the formula:
A = \frac{1}{2} \times 15 \times 10
3. Calculate the area:
A = \frac{1}{2} \times 150
4. Simplify the expression:
A = 75
Therefore, the total area of the lot is 75 \, \text{square meters}.
