Finding Sides’ Lengths on a Grid

The video tutorial explains how to measure the length and width of a rectangle drawn on a grid made of square feet. By counting the number of unit squares along a side of the rectangle, one can determine its length in feet. The tutorial emphasizes that each unit square has a side length of 1 foot, and counting these squares is equivalent to measuring the length in feet. The lesson concludes by reinforcing the concept of measuring a side of a plain figure using unit squares.
