Question

radha is drawing a dot rangoli (a beautiful pattern of lines joining dots) with chalk powder. She has 9 dots in a raw. How many dots will her rangoli habe for r row? How many dots are there if there are 8 rows? If there are 10 rows​

Answer 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
