4. Sierra has plotted two vertices of a rectangle at \( (3,2) \) and \( (8,2) \). What is the length of the side of the rectangle?

The two vertices plotted by Sierra, \( (3,2) \) and \( (8,2) \), share the same y-coordinate, indicating that they lie on a horizontal line. To find the length of the side of the rectangle, we simply calculate the distance between these two points by subtracting the x-coordinates: \( 8 - 3 = 5 \). So, the length of the side of the rectangle is 5 units! Now, you can imagine this rectangle extending upwards or downwards at these points, making a perfect shape with a lovely width of 5 units. A fun way to visualize it is to think of it as a cozy little "house" you could build on a grid!
