Answer: To calculate the cost of the triangular lot, we need to first find the area of the triangle using the given dimensions. To do this, we can use Heron's formula, which states that the area of a triangle with sides of lengths a, b, and c is given by:
area = √(s(s-a)(s-b)(s-c))
where s is the semiperimeter of the triangle, given by:
s = (a + b + c)/2
In this case, we have a = 188, b = 145, and c = 158. Substituting these values into the formula, we get:
s = (188 + 145 + 158)/2 = 245.5
area = √(245.5(245.5-188)(245.5-145)(245.5-158)) ≈ 12463.15 square feet
Now that we have the area of the lot, we can multiply it by the price per square foot to get the total cost:
cost = 12463.15 × $3 = $37,389.45
Therefore, the lot would cost approximately $37,389.45.
