1. Number of dots in each row = 8 dots Number of rows = r Therefore, number of dots = 8r When there are 8 rows, then number of dots = 8 x 8 = 64 dots When there are 10 rows, then number of dots = 8 x 10 = 80 dots https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Number of dots in each row = 8 dots
    Number of rows = r
    Therefore, number of dots = 8r
    When there are 8 rows, then number of dots = 8 x 8 = 64 dots
    When there are 10 rows, then number of dots = 8 x 10 = 80 dots
