Question

Find the smallest number of lines needed to make exactly 100 squares

Answer 1

400 lines bc 100x4=400

Answer 2

A square has 4 sides, or lines. So to make exactly 100 squares, you will take 100 squares and multiply it by the number of sides/lines a square has, which is 4.

100 x 4 = 400

So to make 100 squares, 400 lines are needed.
