Linda is painting a design. Each tube of paint will cover an area of 51 square centimeters. At least how many tubes of paint will Linda use to paint section c? Note: section c is 6cm
The answers to choose fom are
a) 1
b) 2
c)3
d) 4
I tried 51 divided by 6 ,but it is not coming out to one of the possible answers.

If section c is only 6 sq. cm, then she needs less than 1 tube.
