Well, if you want to make a row of 35 squares, it sounds like you're going for the "squarely" look! Each square has 4 equal line segments, so if you want 35 squares, you'll need a whopping total of 140 equal line segments! That's a lot of straight lines, my friend. Better bust out your ruler and get to work!

To determine the number of equal line segments needed to make a row of 35 squares, we need to think about how the squares are arranged.

Each square has four sides, and the sides of adjacent squares can be shared. So, if we represent each square with a line segment, we can see that two line segments are needed for each square to create its top and right sides.

Since we want to make a row of 35 squares, we need to have 35 line segments for the top and 35 line segments for the right sides of the squares. Therefore, a total of 2 * 35 = 70 line segments are needed to make the row of 35 squares.

the chain is made with 3 lines per square, plus one ending line

3*35+1
