Surveyors typically use a unit of measure called a rod, which equals 16 feet. (A rod may seem like an odd unit, but it's very
useful for measuring sections of land, because an acre equals
exactly 160 square rods.) A surveyor was called upon to find the
distance between a new interpretive center at a park and the park
entrance. The surveyor plotted the points shown on a coordinate
grid of the park in units of 1 rod. The line between the Interpretive
Center and Park Headquarters forms a right angle with the line
connecting the Park Headquarters and Park Entrance.
What is the distance, in feet, between the Interpretive Center
and the park entrance? Explain the process you used to find the
answer.
