If A and B are points located midway across the north and south boundaries, what is the approximate distance (in miles) from A to B?

Question

A territory's perimeter approximates the shape of a trapezoid with these dimensions for boundaries: 330 miles on the north, 525 miles on the east, 445 miles on the south, and 215 miles on the west. If A and B are points located midway across the north and south boundaries, what is the approximate distance (in miles) from A to B?

215 mi

A trapezoid, two labeled points, and a line segment are given.

1. The right side is vertical. It is labeled 525 miles.
2. The top side is horizontal and connects at the top of the right side. It is labeled 330 miles.
3. The left side is vertical and appears to be half the length of the right side. It is labeled 215 miles.
4. The bottom side starts at the bottom of the right side, goes up and to the left, and ends at the bottom of the left side. It is labeled 445 miles.

Answer 1

(0.5)(215 + 525) = ?
