Luiza delivers newspapers in her neighborhood. If you plot the points (−1, 1), (4, 1), (4, −2) and (−1, −2), you will create a representation of the route she takes, in miles. How many miles does her route cover?
The first thing to do in this case is to draw the ordered pairs in the Cartesian plane and join the points. We have then that the resulting figure is a rectangle. We must find the perimeter of the rectangle that is given by: P = 2L + 2W Where, L: long W: width Restoring the values: P = 2 * (5) + 2 * (3) P = 16 Answer: her route cover 16 miles.
