Question

A new street is going to be constructed to connect Main Street, which runs in the east-west direction, and North Boulevard, which runs in the north-south direction, as shown in the diagram below. The construction cost has been estimated at $110 per linear foot, excluding the new intersections. The intersections are estimated to cost $1,450,000 each.

a. What type of triangle is bounded by the new street, North Boulevard, and Main Street? How do you know?

b. Let x represent the length of the new street. What is the name of the formula that can be used to find the value of x? Use that formula to write an equation that can be solved for x.

c. What is the length of the new street to the nearest thousandth of a mile? Convert that distance to the nearest foot. Show your work.

d. Estimate the cost of constructing the new street. Be sure to include the costs for intersections. Show your work and round the cost to the nearest thousand dollars.
